We excel in high-quality Metal Sheets Welding, with capabilities covering diverse welding tech, material adaptability, and strict quality control to meet structural needs across industries.
We handle steel, stainless steel (304/316), aluminum, and copper sheets, using tailored tech welding for high-efficiency large batches, TIG welding for precision (e.g., thin-gauge sheets), and spot welding for automotive/electronic components. Our team supports custom weldments—from flat panels to complex structures—with weld seam tolerance.
Monthly output reaches 20,000 welded assemblies; small-batch custom orders have 5–7 day lead times. Post-welding treatments (grinding, anti-rust coating) are in-house. Every weld undergoes non-destructive testing (NDT) and load tests, meeting AWS/DIN standards for machinery frames, automotive parts, and industrial enclosures.

Welding is a fabrication process that joins materials, usually metals or thermoplastics, primarily by using high temperature to melt the parts together and allow them to cool, causing fusion. Common alternative methods include solvent welding (of thermoplastics) using chemicals to melt materials being bonded without heat, and solid-state welding processes which bond without melting, such as pressure, cold welding, and diffusion bonding.

Metal welding is distinct from lower temperature bonding techniques such as brazing and soldering, which do not melt the base metal (parent metal) and instead require flowing a filler metal to solidify their bonds.
In addition to melting the base metal in welding, a filler material is typically added to the joint to form a pool of molten material (the weld pool) that cools to form a joint that can be stronger than the base material. Welding also requires a form of shield to protect the filler metals or melted metals from being contaminated or oxidized.
Many different energy sources can be used for welding, including a gas flame (chemical), an electric arc (electrical), a laser, an electron beam, friction, and ultrasound. While often an industrial process, welding may be performed in many different environments, including in open air, under water, and in outer space. Welding is a hazardous undertaking and precautions are required to avoid burns, electric shock, vision damage, inhalation of poisonous gases and fumes, and exposure to intense ultraviolet radiation.
