Description

Circular girth welding jig
Technical field
The utility model relates to welding technology field, relates in particular to a kind of weld jig for auxiliary two circular end surface parts butt welding.
Background technology
When needs dock two metal circular end face parts mutually fixedly, conventionally adopt the way of welding to complete, in traditional welding procedure, first will be the contraposition of two metal circular end faces during welding, then just fixing in 2 the formation of first burn-oning of the diverse location of docking site, next armrest drives welding rod or welding gun to weld along docking displacement is moving again, and two metal circular end faces are fixed together, and this welding manner exists following problem:
1) weld seam differentiation problem
Weld seam does not have unified standard, requirement, only rely on and borrow Welder individual's practical experience, the quality that ability to work judges weld seam, because everyone solder technology height is different, hand-motion welding rod or welding gun translational speed speed are uneven, welding quality is difficult to ensure card, there is multiple standards in the workpiece of therefore different Welder's welding, the quality of weld seam is difficult to guarantee unified.In addition, even same Welder, owing to being easily subject to the impact of external environment condition, Welder's the other factorses such as mood, working attitude, therefore can not guarantee the uniform quality of the weld seam of each welding;
2) weldquality problem
Weld seam conventionally there will be width inconsistent, be uneven, the obvious phenomenon of ripple, often also there will be the phenomenon of undercut.In addition, there is many places arcing point, connect acnode in welding one circle, has a strong impact on the presentation quality of welding work pieces.Especially with the part of elbow, its weldquality is Customers ' Legal Right more;
3) operating safety
Armrest drives welding rod or welding gun to move that speed of welding is slow and labour intensity is large, and manual operation easily causes personnel tired, and energy is not concentrated, and causes operating efficiency low, even occurs security incident.
In order addressing the above problem, to have proposed some at present and utilized various sensor and computer technology to realize the method that welding line automatic welding connects, for example: master controller adopts the automatic welding machine for circular seam that motion controller Programmable Logic Controller is key control unit.But the control system that realizes these methods is conventionally all comparatively complicated, higher to Welder's specification requirement, cost of equipment is higher, is suitable for large batch of production.In addition, existing automatic welding machine for circular seam is special welding equipment, mainly be applicable to the welding of rotary work piece, belong to general automatic welding device, product to some special shapes, for example, the circular rings seam welding of elbow and straight tube junction, this automatic welder(welding machine) is difficult to replace traditional manual welding operation.
