WELDER

bottom up GHH-II girth welder is a self-propelled submerged arc welding system applicable for bottom-up and Top-down constructed wall storage tanks. This type Of machine can serve both construction methods. The large tank, metallurgical blast furnace and hot stove which have the large steel construction are made of plate, the joint form of main structure mostly is long linear weld. The construction project is huge, but it’s especially fit for automatic welding. Conventional automatic welding technique hardly achieves the high efficient welding. Automatic submerged arc weld of transverse seam machine is designed for the transverse level linear weld and girth weld, and it is especially suitable for level weld of cylindrical steel structure. Using combined with vertical position gas-electric welding machine, it is the ideal equipment of automatic welding of large steel structure such as oil tank and blast furnace. SGHH-II double sided girth welder is a self-propelled submerged arc welding system applicable for bottom-up and Top-down constructed wall storage tanks.

GLH-II Electrogas welder GLH-II Electrogas welder is high efficient welding machines to weld the vertical jointof tank shell for the thickness range from 8MM up to100MM( AND MORE), only one pass welding needed for the vertical jiont, the effeiceny is 30 times to manual welding. For the plate of 3.2M width and average thickness 25MM, the average welding time is 30 minutes. Our machines welding process is Electrogas ,better than FCAW which need multi-pass welding. The electrogas welding provides different types of operation tractors for different working conditions. Type CLH-II is mainly used for big diameter tank such as oil tank, for work high above the ground. The operation tractor rides on the wall of the tank, moving along the wall to carry out welding at every vertical weld driven by electric machine; Type GLH-II is mainly used for middle and small diameter tank such as blast furnace and hot-blast stove, for low-level working. The operation tractor is hanged on one side of the plate. It can be pushed not only to move along the wall of the tank artificially, but also to move on the ground; Type DLH-II is mainly used in invert construction for tank-shaped objects such as oil tank, for low-level working. The operation tractor is fitted with wheel with absorb device, which can tightly and safely attach to the plate. It can move along special track, and also can be pushed on smooth ground; Type CTLH-II is mainly used for frame welding for hull. It is convenient that it can be laid in the hanged basket when using. Fillet & Butt SAW Welder Fillet&Butt SAW Welde mainly applied in the auto welding of inner fillet & outer fillet, butt seam and lap on the bottom plate of large oil storage tank erection project. fillet & butt saw auto welder” is composed of welding tractor and DC-6001000 constant power source, mainly applied in the auto welding of inner fillet & outer fillet, butt seam and lap on the bottom plate of large oil storage tank erection project, self-propelled by the magnetic The control box of tractor is mounted on the structure of tractor, with four wheels ,the tractor can move forward on the hard surface or optional rail .propelled by magnetic attaching shell,the tractor lean over to angle to fit fillet welding , the angle of roll is based on the position of welding head mounting. centre-of-gravity position is considered to maintain the steady of tractor. blast furance construction Fillet&Butt SAW Welde mainly applied in the auto welding of inner fillet & outer fillet, butt seam and lap on the bottom plate of large oil storage tank erection project. fillet & butt saw auto welder” is composed of welding tractor and DC-6001000 constant power source, mainly applied in the auto welding of inner fillet & outer fillet, butt seam and lap on the bottom plate of large oil storage tank erection project, self-propelled by the magnetic The control box of tractor is mounted on the structure of tractor, with four wheels ,the tractor can move forward on the hard surface or optional rail .propelled by magnetic attaching shell,the tractor lean over to angle to fit fillet welding , the angle of roll is based on the position of welding head mounting. centre-of-gravity position is considered to maintain the steady of tractor.
