Working on bottom-up construction state working on Top-down construction state

Applicable for •Bottom-up •Top-down•Single wall•Double wall •Inside •Out side



Product Catalogue•Vertical Electrogas welder Vertical 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. Specification; thickness：8-100mm type of steel ：all type of steel shape of groove ：V, X position ：Vertical joint width of plate ：1.0-3.2m current ：300-500 A votage ：20-40V power set ： 380v diameter of wires ： 1.6mm flux cored cooling ： water cooling 8m3/h weld head adjustment ： 5 waver : 4 parameter welding speed ：feedback control full speed ：3000mm/min gas ：CO2 30L/min

Model GHL-II for bottom up construction Model DLH-II for Top -down construction

One pass solve •Inside •Outside



Product Catalogue•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.SpecificationRated welding current: 600A\ 1000AMinimum diameter of Inner fillet : >5M Minimum diameter of outer fillet :>5MSpeed: 0—2000mm/min Diameter of wire: standard: 3.2 Optional: 2.4、、4.0、4.8/5.0 Wire reel specification/weight inner D. 300mm/25kg Control cable:15m/piece ( standard ) Welding cable: 15m/piece + ground wire 3m/piece , 120 mm2/piece Weight of tractor: 45kg

Butt welding

Fillet welding



Tank fabrication methodBottom –up The machines hang on the wall of tank ,riding on the edge of shell, bottom layer is fabricated first ,and then crane the machines to ride on the seond layer To weld the seam between the two layers, one layer after another



Tank fabrication method

Top –Down fabricate the top layer, and then use jacks lift up this layer make a gap for the beneathLayer ,put the next layer fill out the gap and use Machines to weld the seam,the machines are Ranning on the rails mounted in the ground

Lift up the upper layer

Weld the seam

Jack system
