Technical specifications

At gas welding the most effective mixture of oxygen with combustible gases. The most effective use of acetylene. Other combustible gases are used in welding parts of small thickness. The acetylene-oxygen gas mixture prevents oxidation processes during welding, since in the weld pool no dissolution of gases such as hydrogen occurs. which leads to the appearance of residual cracks.

Welding difficulties

Significant thermal expansion causes residual deformation; good thermal conductivity leads to increased cooling rates of the weld pool and requires preheating of the metal. High casting shrinkage of the cooling metal can lead to deformation of the weld zone; a · the high sensitivity of molten copper to hydrogen promotes the appearance of water bubbles and the appearance of small cracks and pores.

Welding wire

Before welding, it is cleaned by etching with an aqueous solution of nitric acid or a mixture of hydrochloric and sulfuric acid with further washing in water, after in alkali, and then again in running clean water. After the end of the washing, the wire is dried with hot air. For example, copper electrodes are calcined before welding start, thereby reducing the likelihood of a hydrogen disease.
