Is stick welding stronger than MIG?

Stick welding and MIG welding (also known as gas metal arc welding) are two common welding techniques, each with its own characteristics and different application ranges. The following is a detailed comparison of the strength of these two welding methods:

Characteristics and strength of stick welding

The strength of stick welding can generally reach about 60-70% of the strength of the base material.
The strength of stick welding is affected by many factors, including welding materials, welding process, welding structure and welding environment.
For example, E43 welding rod indicates that the tensile strength of the weld metal is greater than 430 MPa.
Characteristics and strength of MIG welding

MIG welding can produce high-strength welds, and the specific strength depends on the type of metal used, welding parameters, quality of welding materials, and operating techniques.
Under proper welding conditions, MIG welding can achieve the same or even higher strength as the parent material.
For common mild steel and stainless steel materials, MIG welding can achieve high strength, reaching 30,000 pounds per square inch or more.
In summary, MIG welding can achieve higher welding strength under proper conditions, especially when automated production and welding thicker materials. However, stick welding also has its advantages, especially in certain specific applications and materials. The choice of welding method depends on factors such as the specific welding needs, material type, welding position and welder's skills.
