What is welding? What is the difference between ordinary welding
Gas welding is a welding method that uses the flame generated by themixed combustion of combustible gas and combustion supporting gas asthe heat source to melt the weldment and welding material and realizeatomic bonding. Electric welding uses electric energy to pressurize,heat, or both, with or without filler material to achieve atomicbonding of weldments.

Why welders should be steady accurate and ruthless
Welding is like practicing martial arts. The first thing to do is to have as table chassis, that is, a stable "horse step". When the center of gravity is unstable, it is difficult to weld a good weld when shaking.

Elimination of heat pipe in the band structure
Hot-rolled seamless steel tube or by heat expansion of seamless steel metallurgical examination, often found banded structure defects, severe achieve level 4-5. Different parts of the steel pipe sampling inspection results show that the circumferential surface of the pipe band structure is lighter, the bore surface band structure obviously seriously half the thickness of the band structure.

Welding process to reduce welding distortion
The more filler metal, the greater the deformation. Making the correct weld size can obtain small welding deformation and save welding time. The amount of filler metal in the weld should be small. Excessive welding metal will increase shrinkage force and welding deformation.
