What is the safe operation process of the hot melt welding machine

1. Use roller bar or bracket to level the pipe, adjust the concentricity, use clamps to correct the out of roundness of the pipe, and leave welding space.
2. Check and adjust that the data of the welded pipe is consistent with the actual data on the Linfei mechanical welder (pipe diameter, SDR, color, etc.)
3. Mill the welding surface of the pipe with enough thickness to make the welding end face smooth and parallel, and it is qualified if the welding end face reaches 3 consecutive full turns.
4. The unfitness of pipe butt joint is less than 10% or 1mm of the wall thickness of welded pipe; Re milling is required after re clamping.
5. Place the heating plate, check and adjust the temperature gauge of the heating plate (210 ℃). When the bulge height of the circumferential crimping at the welding points on both sides of the heating plate reaches the specified value, ensure that the heating plate is closely fitted with the welding end face.
6. Switch the butt joint, take out the heating plate after reaching the specified welding time, and quickly weld and pressurize the pipe surface.
7. When the cooling time is up, turn the handwheel, loosen the clamping pad, and remove the welded pipe fittings.
