How to Choose the Right Welding Process: MIG, TIG, SAW, or Stick

August 25 02:13 2026

Chengdu, Sichuan, China – August 25, 2026 – Picking the Right Process Matters as discussed below.

Welding jobs are not all the same. Different materials and conditions need different processes. The main welding processes are MIG, TIG, SAW, and stick welding (SMAW). Each one has its own strengths. Each one also has its own limits. Morrow Welding Development Co., Ltd. makes power sources for all these processes. The company has 21 series and over 100 products. It serves steel, shipbuilding, petroleum, and metallurgy. Its products go to Europe, America, Asia, and the Middle East. This article helps you pick the right process for your work.

When to Pick MIG Welding

MIG welding uses a wire electrode that feeds through a gun. It is also called gas metal arc welding. This process gives high speed. It works well for thin to medium thickness steel. It also works for stainless steel and aluminum. MIG welding is good for production work. It needs less skill than TIG welding. Morrow makes many MIG welding power sources. These include the NBC series and DSP series. The DSP-500TG5 does high-speed pulse welding. It gives deep penetration for medium to thick plates. It also gives low spatter for thin plates. MIG welding is a good choice for most shop work. It gives good speed and quality.

When to Pick TIG Welding

TIG welding uses a tungsten electrode. The arc does not melt the electrode. You add filler rod by hand. This process gives clean and precise welds. It is the best choice for thin materials. It works well for stainless steel, aluminum, copper, and titanium. TIG welding gives good control. It makes beautiful welds. But it is slower than MIG welding. It needs more skill. Morrow makes TIG welding power sources. These include the WS7 and WSM7 series. The WSM7 series does DC TIG, pulse TIG, and MMA welding. It supports 80% duty cycle. It works for many applications. TIG welding is the right choice for quality work. It is good for thin metals and critical joints.

When to Pick SAW Welding

SAW welding means submerged arc welding. It uses a wire electrode and granular flux. The flux covers the arc. This gives very high deposition. It also gives deep penetration. SAW welding is good for thick plates. It works well for shipbuilding and heavy fabrication. It gives high speed and good quality. But it only works in flat or horizontal positions. It needs more setup time. Morrow makes SAW welding power sources. These include the MZ7 series. The MZ7 series uses IGBT full-bridge soft-switching technology. It gives over 85% energy efficiency. It supports SAW, MMA, and gouging. Morrow also got a patent for a SAW welding power source for gantry welding. This reduces cable failures. SAW welding is the right choice for thick plates and high-volume work.

When to Pick Stick Welding (SMAW)

Stick welding is also called shielded metal arc welding. It uses a flux-coated electrode. The electrode is consumable. This process is simple and portable. It works well outdoors. It also works in windy conditions. Stick welding works in all positions. It is good for repairs and maintenance. It does not need shielding gas. But it is slower than MIG welding. It also produces slag that needs cleaning. Morrow makes stick welding power sources. These include the ZX7 series. The ZX7-400-B is made for cellulose electrode down welding. It gives deep penetration and strong welds. It is widely used for oil and gas pipelines. Stick welding is the right choice for field work. It is good for outdoor and remote jobs.

How to Make the Right Choice

Picking the right process depends on several things. First, look at the material type. Second, look at the material thickness. Third, look at the job location. Fourth, look at the production speed you need. Fifth, look at the weld quality you need. MIG welding gives good speed and quality for most shop work. TIG welding gives the best quality for thin and critical work. SAW welding gives the highest speed for thick plates. Stick welding gives the best portability for field work. Morrow Welding Development Co., Ltd. makes power sources for all these processes. The company has served the steel, shipbuilding, petroleum, and metallurgy industries for many years. It has stable markets in Europe, America, Asia, and the Middle East. The company can help you pick the right process for your project.
