The efficient and high grade solder that bury arc

8mm) carbolic stencil steel makes a diameter be 12ft (1ft=304.

8mm) cylinder. Press the makings below dimension with machine of a Plasma Cutting above all, go up in reel machine then roll into a big cylinder. Add up to fore-and-aft juncture solder with MIG solder, make cylinder form housing. Welding line up, external welding line is used bury arc to solder, next housing retroflexions 180, internally welding line undertakes soldering, in order to assure 100% solder frit is deep. This working procedure uses dc to bury arc solder craft. However, because of solder the growth of fast requirement, technical personnel plan employs a balance in next treatment working procedure adjustable communicating square wave welder art. Issue a working procedure to want a norms to be 2-1/2in (1in=25.

4mm) flange and base case solder are together, receive small flange and solder of additionally 3 housing again then. Solder after ending, the housing department branch with tall 10ft is together repeatedly, form a successive 40ft encrust body. Welding line must along every housing periphery by inside outside reaching, undertake soldering. To assure to finish this one job, emperor - George processing factory assembled system of a posture, this system places cylinder go up in a base tubal account, follow through a group use system of cylinder of cam mechanism roll, this system can maintain point of view is unanimous between cylinder and solder but repeatability is operated (if pursue 4) . Graph 4 exterior solder equipment of such welder of a Summit Arc 1250 can solder already of housing inside welding line, can solder again the welding line outside housing. Technical personnel decorated a converter, allow to solder operation in 2 Miller HDC 1500 controls a system, RAD sends silk package, transition has between welding flux funnel and OBT 1200 welding torch. Solder the component is placed in work platform coping, the welding line outside soldering (mix last the first times) , another solders the component is placed use on workshop ground solder inside welding line (if pursue 5) . Two solder greatly the component all can swing at will, the shift that makes fluctuation from beginning to end with benefit at soldering of the position decide definitely. Graph 5 assemble platen, assemble frame reach component sending silk the consistency that this assembles a stage to be able to assure to assemble, at the same time still a few assist device, can eliminate the machine down time when welding line of inside and outside is changed, if move assembles a stage to come over, rotate reach the designated position, undertake soldering operating after that. Save the weld time of 60% to go to flange solder housing (if pursue 6) on need is mixed in cylinder interior exterior undertake soldering (set housing board by certain bevel, the two weldment warm-up that solders need comes 93 ℃ ) . Use DC EP dc to outputting the solder that bury arc, need 5 to solder, solder fast it is 15in/min on average, welding wire norms is 5/32inAWS EM12K. And use same kind of welding wire, employ a balance adjustable communicating square wave craft, parameter is 66%EN +34%EP, welder of Summit Arc 1250 needs 3 to solder only, average solder fast for 22in/min. Graph 6 housing view with 15in/min solder fast solder the cylinder that a diameter is 12ft need 60min, use craft of old-style DC EP to solder same housing needs 300min the least. To make sure the temperature between the layer is unapt too tall, housing still needs time to undertake cooling, so actual operation time still may be met longer. And the balance is adjustable type square wave solders craft needs 123min only, and operate hot input measure small, solder talk is little, need not await weldment refrigeration, use solder dose is little. Hot input quantity is exorbitant will cause various problems, if the weldment when refrigeration is contractive, according to the regulation housing allows tolerancepublic errand to be 1/4in. Solder in use dc when craft, if do not control the temperature between good layer, flange can be head and shoulders above formulary public errand because of drawing phenomenon, will be orthogonal no longer between flange and housing, and not recoverable. Iceberg one horn because the run time of housing project is limited, emperor - personnel of technology of plant of Qiao Zhigang construction solders newly without adequately dug systematic feasibility. Should solder what the system can do is more than these, use this kind of craft general for example the armor plate butt joint with two thick 5/8in, every solder together, can come true of 100% solder frit is deep, assure to solder at the same time exterior width has 3/4in only. Need not need groove so, avoid to waste the input with solder material and overmuch generation. Another technology upgrades even if Miller's number makes up form HDC controller, this controller can be set beforehand and the lock solders 12 sets surely program. Emperor - controller of plant of Qiao Zhigang construction expresses, make up form HDC controller through using Miller's number, can solder for what the client offers high quality not only, and the quality stability that can assure whole job flow. Through beforehand set locks up calm job parameter, go to these parameter application after that in working flow. Besides time of can managing operation, miller buries arc solder automatically to solder the technology still can make steel structure factory productivity is stronger, enhance the market competition ability of the product greatly then.
