Q:Waterproof electrode, waterproof welding
Example: Water supply with steel pipe Company Caoxi - central pumping station Huang She Lou 800 mm steel pipe leakage. The excavation, inspection found: weld welding position of about 600 - 700 mm cracking, the bottom of the crack width of nearly 15 mm. Pipe sewage for a reason can not be drained, the water depth of about 200 mm, the sewage at a long flow. As the top of the water welding is different from the underwater wet welding, even with the T202 underwater electrode, the front overflow will break through the arc bubble, and the welding can not be carried out.For the commonly used electrode, the water will quickly cool the electrode coating, Condensation, no longer arc. ?In order to offset the water pressure from the leak and compensate for the heat loss of the welding water cooling, the use of small diameter electrode (2.5-3.2 mm) welding current 1.5-2 times larger than usual, short arc welding. From the direction of welding to be accurate, action to be fast, arc is not easy to use scratch method, easy to use touch method. Special attention, must not be convenient at the location of welding. In this case, when the weld is gradually reduced and concentrated in the lowest part of the welding position, the water is more urgent, welding will be more difficult (in general, the pipeline should be welded from the welding position. 1, the 12 mm of steel into the crack, the outer surface and the steel than the wall flat. , At the bottom of the pipe will be reinforced and pipe wall spot welding, then the steel into the crack by paragraph, every 50 mm on both sides of the spot welding. When the crack is too small can not break into the steel, for smaller steel bars, until the basic fill the cracks, control the gap to be welded less than 3 mm. Then the amount of water is clearly reduced, can be formally welded (it is necessary to wet gloves, clothes for dry, to prevent electric shock)
Q:What is the impact of TPO waterproofing membrane welding performance?
Factors affecting the welding performance of TPO coil mainly in the following areas: 1. Material melting point and welding window;
Q:Surfacing isolation layer is the application of what, how to achieve surfacing isolation layer weld.
Surfacing as a material surface modification of an economical and rapid process, more and more widely used in various industrial sector parts manufacturing repair.
