ne when welding? How to adjust the fire?

Answer:

If use electric welding, not only the turning point of the turning point of the lathe, but also to use carbon steel welding electrode welding, the welding finish should also be cooled and so on.
The steel of lathe knife is very special, if can be welded by electric welding, it is the best. For gas welding, when welding the blade easily oxidized, will affect the service life of cutting tool, and after welding, lathe tool is easy to annealing, cause the lathe tool hardness is reduced, and even cause tool scrap.
When the acetylene is fired, the oxygen is slowly opened, the blue outer flame is shortening, and the outer flame is three times the length of the flame. The flame is called "mild carbonation" and is called "triple carbon flame". "Mild carbonization" is the best proportion of oxygen and acetylene when welding.
