Such As How To Correct The Automatic Seam Welding Machine
Such as how to correct the Automatic Seam Welding Machine
One, find a good standard
We know that to really welded steel drums to ensure the quality of the weld, master the welding current, welding pressure, welding speed three elements is very important, they have a direct relationship between the same current in the case of setting the welding pressure changes , The current will change. Because when the welding pressure increases, the upper and lower pad to improve the pressing force, two layers of steel plate to improve the contact tightness, its resistance will be reduced, the heat will be reduced, then we must increase by increasing the current Its heat, and vice versa, the resistance increases, and its heat increases, and the current must be reduced. If the speed changes, through the heat between the two units of the heat is also changing, so the speed is fast, it is necessary to increase the current, the speed is slow, it is necessary to reduce the current. Under normal circumstances, the welding pressure is determined by the thickness of the steel plate, a certain thickness of the steel plate to choose a certain welding pressure. In the actual production process, in the steel plate thickness difference is close to the case, generally do not need to adjust the welding pressure, but in changing the welding speed, the welding current is generally higher or lower, so the operator must master Good welding specifications of the three elements, first of all to find a good standard, in the large quantities of welding generally do not easily change the specification, which is the stability of the quality of steel drum welding has a very important factor.
Second, find the benchmark
In the use of semi-automatic semi-automatic seam welding machine, automatic automatic seam welding machine, due to the upper and lower welding wheel wear, steel drum specifications change, the operator must be fully automatic seam welder position adjustment , Our operators will find the steel drum welding position of the reference point, the center point, where the need to increase the location, which places need to lower the position, know its principle, whether it is semi-automatic automatic spot welding Machine or automatic automatic seam welder, as long as properly adjusted, can be very smooth to meet the welding requirements, otherwise it is likely to cause correction time is very long, defective rate is high, and even some can not find the correcting direction , Resulting in poor stability of Automatic Seam Welding Machine, defective rate increases, the quality of welding have a direct impact.
Third, find the fault location
In the process of automatic seam welding machine, there are quality problems, operators often can not find the problem of the site, blindly adjusted, time-consuming and laborious, so must find the location of the fault is particularly important, whether it is semi-automatic spot welding or Automatic welding machine, the general problems are in the copper roller (waist drum) compression degree, the flat outside the pad, the barrel in the process of smoothness, the mechanical structure of the position, and welding "three elements "The choice of, for example, the pressure adjustment of the copper roller, the pressure is too light, easy to take the side, the pressure was too heavy, the barrel through the copper wheel when the resistance is too large, the barrel is difficult to enter the welding area, When the body will appear when the phenomenon of uneven speed, then the heat will be too large or too small, causing leakage. Welding wheel outside the garden will cause the steel drum through the welding area during the poor contact, resulting in weld leakage. Smoothness in the progress of the problem, especially the barrel, the next left and right swing, the same will appear poor contact with the welding area caused by leakage. The mechanical structure of the position of the degree of deviation, there may be barrel deformation, take the size, into the welding area of the resistance. In particular, the "three elements" of the choice of welding specifications, if the specification is not appropriate or choose the appropriate changes to the standard, it is necessary to find the fault site to re-adjust, so the operator or maintenance personnel, must be on the automatic seam welding machine production process In the quality of the problems encountered to find the fault location, and some of the vector solution. How fast is the province to ensure the quality of welding.
