MIG welding produces a backward thrust of the wire, which allows for faster completion of the weld, and is suitable for multi-job and efficiency projects.TIG welding requires a hand-holding of the wire in conjunction with the weld, which provides better control and a cleaner weld, and is suitable for projects that are interested in precision and durability. In this article they will be fully compared and you will also learn which method is best for your project, as well as provide in this article the mistakes that beginners tend to make in both processes and how to solve them.

Conduction welding uses a laser to melt the surface of the metal to create a shallow, wide weld. Keyhole welding, on the other hand, uses higher energy lasers to create deep, narrow welds by creating tiny holes in the metal. Both methods fall under the category of laser welding, which is widely used in aerospace, medical, energy and industrial applications, helping many industries to join metals. They are also used in electronics and semiconductor manufacturing.

At its core,laser welding is a process that uses a highly concentrated beam of light to join materials. When this focused energy impinges upon a material's surface, it rapidly heats, melts, and fuses the parent materials together. Upon cooling, a strong metallurgical bond is formed, creating a weld seam.

Laser welding quality depends on the combined effects of the type of laser, workpiece material properties, material assembly, shielding gas, and environmental control. Optimizing quality means controlling penetration depth, minimizing the size of the heat-affected zone (HAZ), avoiding defects such as porosity and lack of fusion, and achieving consistent weld geometry. This guide organizes key factors, supplemented by experimental tables and comparisons, to assist engineers, technicians, and advanced enthusiasts in adjusting parameters and understanding trade-offs.
