Moreover, it produces precise welds making it widely accepted in the aviation and marine industries. This welding technique requires low power and works at high speed. The pressurized gas forms a hot plasma, which melts the metals together to create solid welds. However, it uses a small arc and permits placing the electrode on the welding torch body. Plasma arc welding is similar to TIG welding in that it uses a tungsten electrode. It is a common technique in construction, shipbuilding, and steel fabrication industries. This welding technique is perhaps the most convenient, as its equipment is compact and portable – easily carried around. As heat is generated, it disintegrates the flux covering the electrode, forming a slag that protects the weld pool from contamination. The process does not use any shielding gas. It is suitable for tough metals like iron and steel. An electric current from the welding power supply forms an arc between the pieces joining metals and the electrode. It is a manual arc welding process that uses a stick covered in flux as an electrode. Stick welding is referred to as shielded metal arc welding. However, it may be time-consuming and requires expertise on the part of the welder. This welding method provides the welder with better control leading to a neat and strong weld. Also, it is ideal for fabricating frames for motorcycles, doors, and feeders. It is a valuable technique for the aviation and aerospace industries. TIG welding is suitable for welding non-ferrous metals like aluminum, titanium, copper, nickel, magnesium, chromium, etc. Like MIG welding, it uses inert shielding gas – argon or helium to prevent atmospheric contaminants and oxidation of the electrode and puddle. Tungsten Inert Gas (TIG) is an arc welding that involves using a non-consumable tungsten electrode under DC or AC to produce its weld. Also, it is a cost-effective technique, as it requires no sophisticated machines. This welding method is the go-to technique in the automotive and home improvement industry. MIG welding creates top-quality welds, and it’s suitable for most sheet metals, such as aluminum, steel, and stainless steel. The shielding gas in the welding gun prevents atmospheric contamination of the weld puddle. The melted wire in the pool causes the joining of the metal pieces. It involves feeding a continuous solid wire electrode into the weld puddle with a welding gun. Metal Inert Gas welding (MIG), also known as Gas Metal Arc Welding. Now, let’s take a comprehensive look at some methods for melding metal sheets. It also provides vital tips to note when welding thin sheets of metal to obtain the best outcomes. This article provides a detailed view of the various methods used in welding sheet metal, including their advantages and applications. There are different sheet metal welding techniques, but do you know which is best for your industrial applications? Therefore, sheet metal welding is an important aspect of metal fabrication. After cutting metal pieces to desired sizes, it is necessary to join them to suit desired shape and specifications.
