Metal Welding Service

Metal welding is widely used in the manufacturing and construction industries to quickly assemble metal parts into the shape and structure you want. Techniques for joining metals or plastics through high or high pressures have a variety of sources of energy, including gas flames, arcs, lasers, electron beams, friction, and ultrasonics.

The metal material to be welded is the key to determining the type of welding technology, so that the most reasonable process is selected for welding.

What Metal Welding?

Metal inert gas shielded welding (MIG), also known as gas metal arc welding (GMAW), is a welding process that forms an arc between the wire electrode and the workpiece metal, heating the workpiece metal to melt and connect it. Tungsten inert gas shielded welding (TIG) is an arc welding process that uses non-consumable tungsten electrode welding. Our welding services include machining, laser cutting, stamping, rolling, hardware installation and finishing, all of which are necessary for efficient manufacturing of parts. We provide customized finished parts to customers around the world to meet your specific requirements and tolerances.

All metals that are aluminum welded can be TIG welded, and aluminum may be the most popular choice process. Aluminum has many favorable characteristics, such as high strength to weight ratio, corrosion resistance, forgeability and thermal conductivity. However, some characteristics of aluminum require special care when welding it. Rest assured, we are capable of handling a variety of materials, and aluminum is no exception. Our rich experience, advanced machines and excellent technology enable us to exceed our customers’ expectations every time.

Strong Manufacturing Capabilities

aluminum alloy Welding products

Aluminum Alloy Welding Service

Aluminum alloy is the most widely used metal material in industrial applications, with high strength and light weight. It is commonly used in aerospace, automobiles, ships, bridges, machinery manufacturing, electrical engineering, chemical industry and cryogenic installations. Aluminum magnesium alloy and aluminum manganese alloy have good rust resistance.

  • Tungsten arc welding: usually used for aluminum alloys, a very wide range of welding methods, but the welding equipment is more complicated and not suitable for outdoor welding operations.
  • Resistance spot welding / seam welding: used for welding aluminum alloy sheets below 5MM, suitable for mass production of parts, with high production efficiency.
  • Pulsed argon arc welding: small welding distortion, small heat affected zone, suitable for thin plate welding, suitable for welding of forged aluminum, hard aluminum, super hard aluminum and other materials.
  • Friction welding: It can effectively avoid the cracks and pore defects caused by fusion welding, and is widely used in the welding engineering of aluminum alloys and aluminum-magnesium alloys.
stainless steel welding service

Stainless Steel Welding Service

Stainless steel contains more than 12% chromium and nickel, manganese, molybdenum and other alloy elements to ensure the characteristics of heat resistance and corrosion resistance.

Austenitic stainless steel with the best weldability is generally selected, and welding methods such as DC argon arc welding, manual arc welding, brazing and soft soldering are used.

  • The shielding gas must be pure so that the welding surface can have no color difference.
  • Reduce the gap between welded parts, the tighter the better.
  • Use welding wire with a smaller diameter.
  • Use a small current, based on the melting point of the welding wire.
  • Proficiency in welding skills, especially in manual welding, skilled technology is very important.
Steel welded structural parts

Steel Welded Structural Parts

Steel is the most commonly used material for metal welding, and different steels have different weldability.

Mulan will recommend the most reasonable steel according to the structural design and use requirements of your product.

  • Low carbon steel: carbon content <0.25%, good weldability, little change in hardness, good plasticity.
  • Medium carbon steel: carbon content 0.25% -0.6%, poor weldability, multi-purpose repair welding of forged parts and cast parts.
  • High carbon steel: carbon content> 0.6%, poor weldability, generally not welded, arc welding or gas welding is usually used for repair welding.
  • Low alloy steel: generally low alloy structural steel with selective strength less than 450Mpa, good weldability,
copper welding products

Copper Alloy Welding Service

Copper and copper alloys have been used by humans for a long time. Now they are widely used in many products in life. They have good thermal conductivity, which is seven times that of steel. , The reason why it is not easy to weld. It has the characteristics of being difficult to fuse, easy to oxidize, easy to generate pores, and easy to generate thermal cracks.

  • Pure copper: TIG welding (thickness 1-10mm), MIG welding (thickness 4-50mm), plasma arc welding (thickness 1-16mm)
  • Brass: TIG welding (thickness 1-10mm), MIG welding (thickness 4-50mm), plasma arc welding (thickness 1-16mm)
  •  Cupronickel: TIG welding (thickness 1-10mm), MIG welding (thickness 4-50mm), electrode arc welding (thickness 2-10mm) plasma arc welding (thickness 1-16mm)
