Zoomlion wheel crane structure welding comprehensive advance robot era

With the engineering crane company QuanTang industrial park structure workshop 11 table welding robot installation complete and formal delivered for use, wheel crane jib, turntable, frame and leg four structure welding process fully into the robot era.

Robot welding process introduction, improve the quality of the weld, the weld seam andry transformers inspection by the traditional manual welding qualified rate of 84% up to 99%. The use of welding robot, still can promote wheel crane structure welding efficiency, especially in the welding seam displays the great advantage. To fifty v / 55 v truck crane frame posterior segment in welding as an example, the manual welding time need 5.5 hours/Taiwan / 2 people, and robot welding just 4.5 hours/Taiwan / 2 machine, efficiency can be increased by 18.2% year-on-year. And the traditional manual welding need workers drilling to the internal shi welding, smoke, dust, strong light, high temperature of the extreme environment, serious harm the operator's physical health, and use robot welding are completely avoid these problems.

High frequency welding machine use rise and convenient safe, but we always carry on the maintenance, enhance its service life, high frequency welding machine must be installed on the good earth end, because of the damp, dust is very sensitive, so should be placed in the appropriate work space. The valves can produce high fever, so do not put in will produce heat machine side, nor device in solar direct exposurestud welding machine to the place, because of the above reasons can affect the function of vacuum cooling.

The difficulty of welding in where? One is the material of high strength, is a plank is thick. The material strength and general to level 390 to more than 800. The high strength steel welding problem, the more so we welding process needs high technology and welding process requirement, also need to experience. Thick plate since mm to 180 mm, very thick, the general welding technology to so thick material may appear a lot of problems. So in ocean engineering steel structure whether offshore loading leg, post. There is a low temperature Stud welding systemtoughness, submarine temperature is very high, this kind of steel structure after welding in low temperature toughness demand is very high, this aspect in general if do well this process would be brittle fracture occurred, if oil field happened this kind of question is that a lot of accidents, are not allowed to appear. In addition, the weldability, welding demand is higher, in addition to its lamellar tearing, fatigue strength have relatively high request, this is the difficulty of welding.
