不同类型的焊接及其应用

金属是地球面上最耐用的材料之一。因此,它在工程中对塑造和塑造金属进行了值得注意的发展,以便每天看到和使用的机器零件和固定装置。金属结构中采用的一个步骤是焊接的,该方法在其中工人在选择点上熔化一块金属的过程,然后用相应的金属件键合。随着时间的推移,发明人已经开发了各种方法来焊接两块或更多件金属。

三种最常见的焊接类型是MIG,TIG和棒。这些方法中的每一种都提供各种各样的方法welding applications。以下文章涵盖了这些和其他焊接类型和定义。

MIG WELDING

金属惰性气体(MIG)焊接是一种用于重金属的手动电弧焊接的形式,交替称为气金属电弧焊接。

WHAT IS MIG WELDING?

What is MIG Welding

MIG焊是metal-bonding metal-shaping process that sends an electrode through a tool gun and applies it to corresponding metal surfaces. To prevent contamination, the welding gun employs a protective gas that shields the weld area. The MIG process is an easy and accessible welding process for garage-based metal workers and hobbyists.

The process works on metals that range from 24-gauge to half an inch thick. MIG welding is popular among metal-working novices because it is a more straightforward technique to learn and master. The MIG wire does not protect metal services from rust or corrosion. Therefore, clean and brush down bare metal parts before a MIG application. To ensure a pure flow of the electrical wire, only use clean metal in the process.

MIG焊接应用

MIG焊接是最常用于重型电弧焊接项目的方法之一。构成城市污水或水系统的一些金属部件是MIG焊接的结果。该过程是管道焊缝的标准。因此,您依靠饮用,烹饪和卫生的水通过管道来通过管道,没有MIG焊接。

Due to the heavy-duty nature of the method, MIG welding is a typical technique in hard facing, which entails welding rough materials onto base metals. You have MIG welding to thank for some of the parts you see on tractors, cranes and other types of rolling stock.

MIG焊接在国家的铁路轨道的制备和组装方面也是必不可少的。由于该方法将厚金属件与不可用的强度加入厚金属件,MIG焊接负责铁路和公共街道轨道,很少需要维护。因此,MIG焊接是运输和商业的主要辅导员。

汽车行业也依靠MIG焊接。在工厂准备和将汽车零部件装配到成品车辆的工厂,他们使用MIG焊接为较重的金属和设备。此外,MIG焊接负责制作沿生产线所看到的工厂设备。MIG焊接也是汽车维修商店的流行方法。

TIG WELDING

Tungsten inert gas (TIG) welding is a manual arc welding process for heavy metals, alternately known as tungsten gas arc welding.

什么是tig焊接

TIG焊接是一种金属粘合工艺,采用钨电极加入另一个金属表面。在过程中,氩气或氦气在施加的表面上形成抗氧化和其他空气结合的污染物的保护屏蔽。使用氦气的应用也被称为蠕动焊缝。大多数TIG应用依赖于中间金属。规则的例外称为自动焊接。

MIG和TIG焊接之间的基本差异是前者依赖于持续的焊丝饲料,而后者依赖于将您指示焊接水坑的焊接棒。

TIG WELDING APPLICATIONS

TIG welding plays a vital role in the automotive industry, where the process is effective at bonding metal parts together for the construction of cars, vans, trucks and SUVs. The tungsten electrodes work well in the factories where workers assemble engine parts from individual pieces of metal, as well as in the plants where auto-body parts get prepared for the assembly lines.

TIG welding is also essential in the construction industry, where the equipment gets transported to worksites and used in the preparation of parts for buildings and public monuments. Many of the buildings you see along the streets and thoroughfares of your community have been the work of construction crews that rely heavily on TIG welding.

The shipping industry also employs TIG welding. The process makes it easier for shipbuilders to join shaped metal parts together for ships like aircraft carriers or cruise liners. If you have ridden a passenger ship or sailed overseas while serving in the U.S. Navy, tungsten electrodes have likely welded the body of each ship in full or in part.

粘焊

Stick welding is a form of hand-driven arc welding used on a range of metals. The process is alternately known as shielded metal arc welding and flux-shielded arc welding.

WHAT IS STICK WELDING?

粘焊是一种金属粘合方法,其中焊剂覆盖的消耗电极将两个金属表面粘合在一起。在钢焊接过程中,在电极和相邻的金属表面之间形成直接或交流。由衰落电极产生的蒸气产生屏蔽气体。人们通常使用该过程焊接钢铁和铁,以及铜,镍和铝。

粘焊APPLICATIONS

棒焊接可以帮助工人完成任务大,几乎任何位置的任务。对于出站应用程序,该过程方便,因为所需的设备是便携式且易于运输的接通修复任务。因此,钢焊经常在纠正难以达到的地点和远程公共建筑物中发挥作用。

Stick welding is also common at outdoor construction sites, where the process makes it easy for work crews to assemble and modify metal parts on the spot. The flux-covered electrodes are wind-resistant, which makes the process convenient in various environments. When a disaster strikes, stick welding is often the method used to repair damaged metal fixtures.

In remote settings, stick welding is one of the most convenient types of arc welding. When workers assemble temporary structures for county fairs and carnivals, stick welding can strengthen and fortify the support beams of tents and fences. For communities that live off the grid, stick welding is one of the most reliable methods for metal repair and construction.

The portability and ease of stick welding have also made it one of the preferred methods among hobbyists and independent craftspeople. Since the approach works with a broad variety of metals, jewelry makers sometimes use stick welding.

所有其他类型的焊接

Throughout most of the industries that employ metal construction, the processes of MIG, TIG and stick welding are the most widely used due to the power, efficiency and versatility of each method. However, numerous other processes can also weld two or more pieces of metal together. So how many types of welding are there? There are many different approaches to welding, including the following 12 methods, a few of which are somewhat related to the three most popular types.

所有其他类型的焊接

Fcaw焊接

Flux-cored arc welding (FCAW) is a method of metal-bonding akin to MIG welding, as both use a continuous electrode. However, FCAW requires a tube-shaped wire rather than a solid one. The technique is suitable for both indoor and outdoor use, as long as the wires have adequate shielding. FCAW is one of the more efficient approaches to arc welding because it uses most of the electrode that goes into the process. Thanks to the shape of the flux-cored wire, shielding gas is not necessary with FCAW. The method leaves little debris and therefore entails only a small cleanup process after completion.

EBW焊接

Electronic beam welding (EBW) is a metal-joining method where electron rays get fired at high velocity to join one surface of metal to another. When the ray hits its target, the affected spot melts just enough to fuse the adjoining piece into place. EBW welding plays a role throughout the industrial sector. The method is especially useful for automotive and aerospace manufacturers, who employ EBW welding to fuse many of the metal parts used in cars, trucks, planes and spacecraft. Due to the vacuum-based nature of EBW welding, the process is safe for emergency work in evacuated buildings and houses.

AHW焊接

Atomic hydrogen welding (AHW) is an old method of metal bonding that has mostly fallen by the wayside in favor of more efficient and effective methods, such as gas metal arc welding. One area in which AHW is still common is in tungsten welding. Since tungsten is highly sensitive to heat, AHW is safe for this process. American chemist Irving Langmuir developed this process following his discovery of atomic hydrogen.

等离子电弧焊接

等离子弧焊,发明于1950年代中期,是a method similar to gas tungsten arc welding. The process employs an electrical current, which travels through a tiny nozzle that cuts through a shielding gas. When you need to weld small areas on a metal surface, plasma arc welding allows for pinpoint accuracy. Plasma arc welding is ideal for welding projects in severe temperatures, as this creates firmer and tighter welds. Aircraft manufacturers use this method, as do independent craftspeople for a range of projects.

ELECTROSLAG WELDING

Electroslag is a process of fast welding that was an innovation during the 1950s. Electroslag welding bonds heavy metal pieces for use in machines and industrial equipment. The process takes place in a vertical position that allows for a clear-eyed view of the work as it takes shape. The method gets its name from the copper water holders contained inside the tool used for electroslag welding. The water stops liquefied slag from seeping into other areas during a welding session.

淹没电弧焊接

One of the less frequently used forms of metal bonding is the process of submerged arc welding, which is only suitable for stainless steel and other metals rich in iron. The process allows for the use of both automatic and semi-automatic means, which renders it quick and efficient. Despite the speediness, the process requires a flux to shield the metal when the welding takes place, hence the name “submerged.” With this cover, people can complete their work without the risk of splatter. Therefore, submerged arc welding is a safe practice for independent craftspeople.

CAW WELDING

Carbon arc welding (CAW) is a bonding method that joins metals by applying temperatures that exceed 300 degrees Celsius. In CAW welding, an arc forms between the metal surfaces and the electrode. The method was once popular, but in recent decades, twin-carbon-arc welding has superseded it.

氧气燃料焊接

氧气燃料焊接是一种采用液体燃料和氧气焊接金属的过程。法国工程师EdmondFouché和Charles Picard在20世纪之交发明了它。该过程中使用的氧气产生的温度施加到金属表面的浓缩区域。氧气燃料焊接在室内环境中进行。

RSW WELDING

Resistance spot welding is an arc welding method in which heat bonds metal surfaces. Resistance from electrical currents generates this heat. RSW welding belongs to a group of welding methods known as electric resistance welding.

RESISTANCE SEAM WELDING

Resistance seam welding is a method that generates heat between the faying surfaces of metals with similar properties. Seam welding starts on one side of a joint and works its way to the other end. The process depends on twin electrodes, typically made of copper.

PROJECTION WELDING

作为点焊的形式,投影焊接是一种定位在特定区域中的热量的过程。该过程在涉及使用螺母,螺柱和其他螺纹金属紧固件以及交叉的杆和电线中的过程中是常见的。

COLD WELDING

Alternately known as contact welding, cold welding is a method that joins surfaces without any heat or melting involved.
