QISUO Offers High-Quality, Efficient & Consistent Welding Process for Your Orders

There are many types of welding process such as resistance welding, TIG welding , MIG welding and gas metal arc welding during industrial manufacturing. Here we are pleased to introduce the main types we use in our production.
Products We Welding

QIUSUO has advanced welding equipment and multiple welders on staff at each service center. Our welders are skilled and qualified. We are keeping on providing high-quality MIG, TIG, and arc welding services for your customized products. The mainly products need welding as follows.

  • Stainless steel welded wire mesh, and other metal wire mesh
  • Perforated metal deep process into cylinder, baskets, filter elements
  • perforated metal safety gratings tread
  • Wedge wire screen and wedge wire screen deep processing products including DSM screen, rotary screen, nozzle filter, T intake screen, solid-liquid separation screen, etc.
Material Grades We Welding

Our welding services are available for the following metals:

  • Stainless steel. Available in a variety of grades. Stainless steel consists of at least 11 percent chromium in addition to other elements such as nickel, copper and molybdenum. Stainless steel of various grades enjoys good weldability, making it an excellent choice for custom fabrication projects. The most commonly used welding method is manual arc welding, followed by resistance welding (ERW), MIG, TIG/GTAW welding.
  • Nickel alloys. Welding nickel alloys require additional protection against oxygen and other contaminants, which lead to porousness, cracking and stress corrosion. The most commonly used welding methods are TIG/GTAW and MIG welding.
  • Aluminum. Available in 3003, 5052 and other alloys. All aluminum alloys we work with are easily weldable for custom fabrication purposes. Depending on the thickness of the section, our technicians will typically use GMAW or GTAW to form the bond.
  • Carbon steel. MIG welding is mostly done with carbon steel. But Stick welding, TIG welding processes can be done as well.
  • Galvanized steel. The most commonly used welding method is manual arc welding and GMAW welding.
Resistance Welding (ERW)


Resistance welding, sometimes called electric resistance welding (ERW), is a process by which metals can be joined together by applying pressure and conducting a strong electric current through the metal combination to heat up the welding joint and melt the metals, forging them together. There are many resistance welding processes with different uses.For example, spot welding is the most economical and suitable method for stainless steel welded wire mesh; Straight welding and butt welding are adopted for welding perforated metal tubes; Resistance welding is often adopted for stainless steel filter cloth welding. Every product has its most suitable welding process.


  • Similar and dissimilar metals are capable of being welded
  • Highly automated
  • Efficient with high production rate and high welding rate
  • Cost-effective
  • Environment-friendly, produces little waste or pollution
  • No need for filler metal or extraneous materials such as rods, fluxes, inert gasses, oxygen, or acetylene are required


  • Complex and often high-cost machinery – a resistance welding machine generally requires a high level of technically trained personnel to use.
  • The thickness of the work piece is often limited.
  • It is less efficient for high conductive materials.
  • High electric power required

Tungsten inert gas (TIG) welding, also known as gas tungsten arc welding (GTAW), is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. GTAW/TIG welding is typically used on thin strips of stainless steel, aluminum, copper and nonferrous metal alloys. Besides, it is often used in aircraft and industrial manufacturing where high strength and precision are required, for example, TIG welding is often adopted for processing flat wedge wire screen panels, safety grating and fabricated wedge wire products.


  • Argon gas can effectively isolate air, plus it does not react with metal, so high quality welds are obtained.
  • It is suitable for small scale operation and repair work.
  • It can be used for almost all kinds of metal connection.
  • It can control the heat input very well, so it is a good method for connecting thin metal sheet and backing weld.


  • Tungsten electrode shall not carry too much current.
  • This welding process also requires skilled operation method and time, the efficiency is relatively low.
  • Argon gas as shielding gas is more expensive.

Metal inert gas (MIG) welding or gas metal arc welding (GMAW) is an arc welding process that uses a consumable wire electrode and shielding gas. It generally uses argon gas, helium gas or their mixture as shielding gas. Its most notable feature involves the use of a gas to shield the workpiece metal. This helps keep out contaminants and speeds up the welding process without compromising quality. MIG welding was originally developed for bonding aluminum alloys, but is currently used on steel, nickel alloys and a range of other metals. For example, this method is often used for welding wedge wire screen cylinders


  • Form a better weld.
  • Compared with TIG welding, it has a higher production efficiency.
  • With inert gas protection, it can weld almost all kinds of metals, and has a wide range of applications.


  • MIG welding is always carried out indoors, which limits its practical applications in remote repair and maintenance.
  • Base metal requires strict cleanness treatment and is sensitive to oil and rust.
  • It has poor resistance to wind and is not suggested to be carried out outdoors.

The Differences Between MIG and TIG.

Composition Argon gas mixed with a small amount of active gas as shielding gas, consumable electrode Pure argon gas as shielding gas and tungsten electrode as non-consumable electrode
Welding wire supply Welding wire is supplied in rolls or coils by winding Welding wire is supplied in straight strips at a certain length.
Applicable material Suitable for welding stainless steel, aluminum, magnesium, copper, titanium, pick and nickel alloys. Suitable for welding alloy steel, aluminum, magnesium, copper and its alloys, gray cast iron, various bronze, nickel, silver, titanium and lead.


Stick welding or shielded metal arc welding (SMAW) is a manual welding process commonly referred to as stick welding. It is one of the simplest and most straightforward types of welding, and is commonly used in construction, repair and manufacturing applications. The stick welding process is quite versatile and is used to join steel, stainless steel, iron, nickel and copper alloys, and more.


  • Welding can be carried out at any places both indoors and outdoors.
  • Fast welding, low cost.
  • It is an economical choice for customized welding projects.


  • The welding process is dirty and messy.
  • Stick welding is not suitable for reactive metals like zirconium, titanium, or columbium because the lack of shielding allows oxygen to contaminate the weld.
Flux-Cored Arc Welding (FCAW)


Flux-cored arc welding is similar to GMAW but involves the use of a flux either in place of, or in addition to, a shielding gas. This flux is continuously fed through the electrode and acts as the main form of protection against atmospheric contamination.Materials commonly associated with flux-cored arc welding include stainless steel, low alloy steels, high nickel alloys and other metals.


  • No welding slag is produced, no flux is added.
  • High welding efficiency
  • No preheating is required before welding and no heat treatment is required after welding.
  • FCAW is more suitable for outdoor uses and connecting thick materials than MAG.


  • Complex welding wire manufacturing process
  • Welding wire surface is easy to rust and powders are easy to absorb moisture. So, the welding wire must be stored in accordance with strict management requirements.
  • Inexperienced welders may experience issues such as incomplete fusion, weld cracks or damage to the contact tip.
