1.8.3 The excess glue on the floor surface should be erased in time.
1.8.4 After 24 hours, the grooves and welds will be carried out.
1.9.1 The slot must be made after the glue is completely solidified. Use the special grooves to open the groove along the seam, to make the welding firm and open seam not to be transparent, and suggest that the groove depth is 2/3 of the thickness of the floor.
1.9.2 At the end of the opening, please open the seam with the same depth and width.
1.9.3 Before the weld, the dust and debris left in the slot shall be removed.
1.10.1 A manual welder or automatic welding machine can be used for welding.
1.10.2 The temperature of the torch should be set at about 350 degrees.
1.10.3 With the proper welding speed (the welding electrode is melted), the electrode is pressed into the open slot with constant speed.
1.10.4 When the electrode is semi-cooled, the solder or moon cutter is used to cut the electrode above the surface of the floor.
