Problems solved by technology

If the actual gap is too large, it will affect the welding quality, and it is very easy to cause a vicious accident of broken belt at the weld, so it must be stopped to deal with it

Embodiment Construction

[0011] When the actual weld value is inconsistent with the set value, and the deviation value is relatively fixed, gap compensation can be performed. For example, if the welding seam is set to "0.3mm" and the actual welding seam is "1.0mm", then it is necessary to enter "0.7mm" in the compensation amount dialog boxes for the drive side and the operation side of the entry fixture on the "Gap Compensation" screen. The compensation amount, so after compensation, the actual sheared weld is "0.3mm".

[0012] Under normal conditions, after being cut by double-edged scissors, the distance between the head and the tail is 150mm, and if the weld seam of the MIG welding machine is set to 1mm, the inlet clamp needs to move the head of the steel strip forward by 149mm;

[0013] After the head and tail are docked, if the actual gap is inconsistent with the set gap, gap calibration is required. For example, if the welding seam is set to be 1mm and the actual welding seam is 2mm, then the w...

Abstract

The invention relates to the field of welding, in particular to a quick compensation method for weld gaps of MIG (metal-inert gas welding) welding machines. The method includes the steps: step one, checking widths of actual weld gaps for many times to obtain width values di, and calculating an average value d0; step two, if the absolute value of (di-d0) / d0 is smaller than 5% and d0 is not equal to dq, performing gap compensation, wherein the compensation value is conform to dq-d0, i refers to natural numbers, and dq refers to set values. According to the quick compensation method for the weld gaps of the MIG welding machines, accurate compensation of the weld gaps can be completed quickly without halting, service lives of mechanical parts can be prolonged effectively, maintenance outage time is shortened, and operating ratio is increased.

Description

technical field [0001] The invention relates to the field of welding, in particular to a method for quickly compensating the welding seam gap of a MIG welding machine. Background technique [0002] The welding machine at the inlet section of the silicon steel normalizing pickling unit is the key equipment to ensure the continuous production of the unit. The welding machine is a MIG (metal inert gas shielded welding) butt welding machine. The welding material is cold-rolled non-oriented silicon steel with a thickness range of 2.0 ~2.7mm. The welding machine is specially manufactured for TISCO by GUILD Company of the United States. The whole machine adopts the CompactLogic5000 series PLC control system of AB Company, and the control of the butt weld is completed by the Ultra3000 servo system. [0003] In the actual production process, due to the wear and tear of the mechanical parts of the steel belt head fixture and the accuracy of maintenance and installation, the weld seam...
