HSJ sheet metal welding comes with various types of sheet metal welding, including gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), and resistance welding.
Typical types of sheet metal welding processes including, MIG welding, TIG welding, resistance welding, projection welding, robotic MIG and TIG welding, and laser welding on various metallic and aluminum alloy surfaces as well as on stainless steel and iron.
MIG welding
MIG welding, also called MAG welding, is a continuous wire welding process where a shielding gas ensures firing bath protection. MIG or MAG welding is used where high productivity and high flexibility of use are required. While MIG welding requires the use of inert gas, MAG welding is carried out through an active gas. MIG welding can be also performed on thin metal, such as thin steel or aluminum.
TIG welding
TIG welding is one of the most popular welding methods since it provides high-quality components. Especially indicated to weld thin parts, it can be used for both continuous and spot welding.
Resistance welding
Resistance welding is a metal fusion welding technique where the material is heated by electrical resistance. Generally used to weld iron and steel, resistance welding guarantees high-quality standards on welded components while ensuring time and cost savings. If you want to learn more about resistance welding, we will explain everything to you.
Projection welding
Projection welding requires studs to be placed on the metals to be welded. During the metal welding process, the welding current is focused on the stud that heats to obtain complex welds, with final results that ensure excellent quality at low costs. Basically, projection welding is a type of resistance welding that uses projection.
Robotic TIG MIG MAG welding
Robotic welding is performed by programmable industrial robots. Mainly used in situations that require repeated welding, it guarantees repeated precision which is hard to achieve with manual welding. Greater precision and higher productivity are the main advantages of robotic welding.
Laser welding
Laser welding allows metals and metallic alloys to be welded, creating a thin and deep weld, with reduced heat deformations thanks to the reduced heat, even on materials that could not otherwise be welded. Precision, cleanness, minimal heat input, and fast manufacturing are just a few of the advantages of laser welding.

Aluminum welding
Renowned for its ductility, lightness, and oxidation resistance, aluminum is employed in every sector in which these qualities are required, such as the aerospace sector and the transport sector. HSJ is focused on various types of aluminum welding: aluminum MIG welding, aluminum tig welding, and other welding processes to manufacture aluminum according to the desired output.
Stainless steel welding
Stainless steel is a special steel alloy that boasts important qualities such as rust resistance, corrosion resistance and high hygiene standards. For this reason, stainless steel is widely employed in the food industry. HSJ provides stainless steel welding services for any specific requirements and offers three different services of stainless steel welding.
Welding thin sheet metal demands a delicate touch and specific methods compared to thicker materials. Thin metals are more prone to warping and burn-through, making it essential to employ the right equipment and techniques. Both TIG and MIG welding are suitable for welding thin metal sheets, but when working with extremely thin stainless steel or aluminum, the TIG method takes precedence due to its exceptional heat input control.
The thinnest sheet metal that can be welded depends on several factors, including the welding method, the skill of the welder, and the specific application. Generally, welding very thin sheet metal can be challenging because of the risk of distortion, burn-through, or warping. However, experienced welders can work with extremely thin materials.
TIG (Tungsten Inert Gas) welding is often preferred for welding thin sheet metal because it provides more precise control and lower heat input compared to other welding methods like MIG (Metal Inert Gas) welding. TIG welding can be used for sheet metal as thin as 0.010 inches (0.25 mm) and sometimes even thinner.
With advanced welding techniques and specialized equipment, some welders can work with materials as thin as 0.005 inches (0.13 mm) using TIG welding. However, it's essential to keep in mind that handling such thin materials requires a high level of skill, experience, and attention to avoid damaging the metal or producing weak welds. Proper preparation, fit-up, and welding techniques are crucial when working with very thin sheet metal to achieve successful and durable welds.
HSJ is a reputable sheet metal welding manufacturer based in China. With a team of highly skilled and experienced welders, we take pride in delivering top-notch sheet metal welding services to our valued customers.
