Metal Welding Technical Support 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.


Mulan metal welding factory can weld metal materials such as stainless steel, aluminum alloy, copper, iron and carbon steel. All welding operators hold a license to get formal production safety training.


The Mulan metal welding plant has the most advanced robotic arm welding machine and many advanced welding equipment. Strong manufacturing capabilities and reliable quality. Fast delivery and high quality products are what mulan can do for you.

As a full-scale metal parts manufacturer, we provide the most professional metal welding processing technical support and product production services, focusing on metal welding services for 30 years, passed the ISO9001-2015 standard audit, and the products comply with the RoCH standard.

Welding is widely used to transport petroleum, water, milk, and to manufacture welded pipes and pipes, chains, liquefied petroleum gas cylinders, and other items. Large-scale metal projects such as steel structure components, bridge steel structures, construction machinery parts, and pressure storage tanks. The metal casings of steel furniture, doors, door frames and door frames, cabinets, refrigerators, washing machines, microwave ovens, and auto parts are all welded.

Stainless Steel Welding

Stainless steel has excellent corrosion resistance and processability and is widely used in the industry today. Mulan's most common welding products are stainless steel welding products. The correct welding methods and techniques ensure the high quality of the welding products.

Stainless steel welding is divided into Austenitic Stainless Steel, Martensitic Stainless Steel, and Ferritic Stainless Steel.

Extensive experience can avoid deformation and cracking of welded stainless steel products.

 Aluminum Alloy Welding

Soldering aluminum requires high power welding and a very clean, oxygen-free surface that will make the welds cleaner, easier to handle, prevent metal pooling, and create surface tension when melted. It is also a good idea to preheat the aluminum before the actual soldering because it is easier to solder.

Carbon Steel Welding

Carbon steel is a very common metal material with low price and excellent public welfare performance. It is widely used in manufacturing and industry. Common large steel structure products are welded with carbon steel materials. The properties of the material can often be altered by carbon steel heat treatment to increase hardness, toughness or processability. Can better serve humanity.


Due to the carbon content of carbon steel materials,

it can be divided into: low carbon steel (WC ≤ 0.25%), medium carbon steel (WC 0.25% - 0.6%), high carbon steel (WC > 0.6%).


Due to the different carbon content, the welding performance of the material is also different. The higher the carbon content, the harder the material and the more difficult the welding. Commonly used low carbon steel has good welding performance. We rely on rich experience in welding products to avoid cracks in welding and ensure the strength of carbon steel welding products.


Mulan is very good at welding carbon steel materials, and carbon steel welding products are delivered to customers almost every day.

Mulan offers a full range of carbon steel welding technical support and product production solutions, you can send me your design and we will implement your project.
