Embodiment Construction
[0033] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0034] The embodiment of the present invention provides a kind of twin-wire welding method, and this method is applicable to EQ70 high-strength steel, such as figure 1 As shown, the welding method includes:
[0035] Step 101: Process welding grooves on each workpiece.
[0036] Step 102: Assemble the welding grooves of the workpieces together.
[0037] In the above implementation mode, when two workpieces need to be welded together, the welding grooves of the two workpieces can be butted together, and the welding grooves of the two workpieces can be positioned and docked by means of clamping tooling or spot welding Together, the specific positioning manner is not limited in this application.
