FAQ

What should be paid attention to when welding the air conditioner copper pipe welding machine?

The copper wire of the air conditioner is not long enough to be welded and connected. Will not affect the effect. The method is: after the direct cutting off, the connection head is connected, after connecting, welding, welding is good.

What is the welding machine for glass fibre reinforced plastic cable protection tube?

The glass fiber reinforced plastic material joint is only suitable for bonding and riveting. It can not be welded, so there is no special welding machine.

Which brand is the best for plastic pipe welding machine? How to ensure the quality of PE pipe welding machine?

Plastic welding is of course with the Swiss LEISTER brand well, can use the mirror to PE pipe welding butt welding

How to weld the air conditioner copper tube welding?

How can the air conditioning copper tube and copper pipe be welded?Copper tube and copper tube welding is generally used silver electrode (its silver content is 25%, 15% or 5%) or copper and phosphorus series welding rod, they all have good fluidity, do not need welding flux. Specific welding procedures are as follows:1) welding copper tube processing: expansion and deburring, old copper pipe must also use abrasive paper to remove oxide layer and dirt. When the diameter of the welded copper pipe is different greatly, it is necessary to clamp the pipe with big diameter in order to ensure that the gap between welds should not be too large.2) nitrogen filling: the copper pipe is filled with nitrogen to carry out welding, which can make the inner wall of copper tube bright, clean and oxide free, so as to effectively control the cleanliness of the system.3) open the welding torch, adjust the mixture ratio of oxygen and acetylene, and choose neutral flame.4) first heated by the flame tube insertion, slightly hot after the flame moves outward a little casing, heating the pipe when the pipe joint uniformly heated to the welding temperature (micro solder (red), adding silver electrode or phosphorus brazing). By the solder melting temperature, and flame temperature maintaining outer flame pipe joints, and not using pre solder melt drip welding joints, then heating welding, otherwise it will affect the strength and density of joints.5) remove the flame and close the torch. Check the quality of the weld. If there is a gap or a sand heel in the weld, re weld the weld
