Embodiment Construction
[0018] The present invention will be further described in detail below in conjunction with the examples.
[0019] The frame member of the present embodiment includes a main pipe and a pipe to be welded vertically with it, and its process steps are as follows:
[0020] 1. Cut the liner pipe with the same diameter as the pipe to be welded to 50mm, and chamfer at 45 degrees;
[0021] 2. Put the end of the pipe to be welded into the heating box, take it out when the reading of the temperature control meter reaches 240°C, and put it into the liner clamp for clamping;
[0022] 3. First heat the lining pipe to 100°C, then align the chamfered end with the heating port of the pipe to be welded, and then step on the hydraulic ejector switch to slowly push the lining pipe into the pipe to be welded until the outer ends of the double pipes are even;
[0023] 4. Carry out arc milling at the end of the double pipe, the radian is the same as the outer diameter of the main pipe, and chamfer ...
