The welding is good, 1-3 months to start.
To carry out the welding operation, we must do a good job of safety measures, leather gloves, aprons, arm guards, it is important to wear a good mask, the mask is the kind of light can be changed, so that not only can protect the eyes, but also can be very clear to see the position of the welding channel, this is very important.
Welding process, subject to must be stable little by little to promote the welding torch, with a fixed surface to support the hand or with the other hand to support the welding of the hand, so that welding out of the weld is uniformly distributed, will not bend, affecting the beauty.
Two welding precautions
Two welding is generally used to single-sided welding double-sided molding process, usually using a v-shaped bevel, the bevel and its surroundings to remove the bevel and rust and reveal the luster of the metal, the assembly, according to the specific circumstances of the amount of deformation reserved for the anti-deformation.
When the bottom of the bevel hole diameter of 3~4mm, normal welding. Welding according to the gap and melt hole changes in the welding torch swing amplitude and welding speed, as far as possible to ensure that the diameter of the melt hole remains unchanged, and to ensure that the weld channel is flat. After welding, clean the surface of the weld channel.
