1. Why there is demand on metal plate joint from the Plate Butt Joint Welding Machine?
1) Steel plates produced from Steelworks usually have format size of (2~5) m width by (6~15)m length, within thickness range of 6~40mm (Medium and thick plate). It can meet demand on majority of common seen application;
2) On the other hand, in many large application sites, such as Machine Tools Manufacturing Industry / Infrastructure Building/ Civil Engineering/ LPG (Liquified Petroleum Gas), longer and or wider steel plates are necessary to be used as raw materials for these big projects. Under these conditions, plate flat butt joint is a requisite step for getting longer and or wider plates;
3) There is conventional way of plate butt joint process which will be discussed below in item 2. And, over the past decades, the equipment of Plate Butt Joint Welding Machine (Flat Butt Welding Machine) brings along reformation on the “old” plate butt joint technology, thanks to its melt thru welding, which brings merits on quality/ productivity/ manufacturing cost for customers with plate butt joint demand.
2. Conventional Plate Butt Joint Process without Flat Butt Welding Machine:
Before the development of Plate Joint Welding Machine, traditional steel plate joint process is like this:
1) First, make welding groove of X/Y/K bevels to make prepare on butt welding;
2) Following that, weld one side of joint seam between the 2 pieces of steel plates;
3) Then, flip the 2 pieces of half-finished joint plates 180°, making the original bottom face turned into top face --- This is arduous, dangerous and toilful job considering size and weight of the joint plate. Especially for thick metal plates with thickness 30~40mm;
4) The fourth, perform carbon gorging on the inverse side of joint --- This is for removing the welding slag generated from the first face welding;
5) The final step, perform butt welding on the reverse side of joint;
You can check from above that the entire complete conventional butt welding process of metal plates needs utilize two kinds of process equipment (Edge Milling mMchine and Ordinary Plate Joint Welding Machine) as well as handling equipment for overturning and transferring the half finished workpiece.
3. Usage and Working Steps of Plate Butt Joint Welding Machine:
1) Adopting the technology of melt thru welding, which is kind of fully penetration welding with effect of single side welding and double side forming, this Flat Butt Welding Machine is for the above mentioned plate flat butt joint purpose, but with much safer, simpler and streamline process steps, and more excellent welding quality: Just load on the two pieces of metal plates for joint onto input conveyor of this Plate Butt Joint Welding Machine, and without any other flipping job involved, with the one time workpieces going thru this Plate Butt Welding Machine, you get the finished joint plate with superior quality;
2) This MP Flat Butt Welding Machine makes the above mentioned 5 steps into 1 step thanks to the large current melt thru welding technology. And, because of water cooling copper pads at the reverse side of the steel plates, the butt joint welding seam formed at the reverse side of the workpiece also has good finish and strong strength. This Plate Butt Joint Welding Machine improves plate joint process quality and efficiency greatly. Please check below item.
4. Advantage of Plate Butt Joint Welding Machine:
1) Surefire Safety from the Flat Butt Welding Machine:
By means melt thru welding, the original hard and risky steel plates overturning step is removed. The entire working process of the Flat Butt Welding Machine is safe and easy. There is no strenuous work involved;
2) Remarkable Quality from the Flat Butt Welding Machine:
The melt thru welding in Plate Butt Joint Welding Machine boosts superior welding quality: The formed welding seam not only has higher intensity than base metal, but fully penetration welding and wider cover face;
3) 40%~ 50% Higher Productivity and Lower Manufacturing Cost from the Plate Joint Welding Machine:
With the help of melt thru welding, this Flat Butt Welding Machine completes the plate butt joint with solitary critical step of butt welding, and optional edge chamfering step as the case maybe. Unlike the conventional butt joint procedure, as customer of this Plate Joint Welding Machine, you do not need to fret over the risky and time consuming task of metal plates handling any more, as well as carbon gouging/ the second face butt welding. So that the total Cycle Time in the Plate Butt Welding Machine is reduced 40% ~ 50%; The corresponding variable cost of manual labor/ Machine running cost are also decreased in large extent;
4) Purchase one set of Plate Butt Joint Welding Machine to get the function of two Machines:
This Flat Butt Welding Machine has triple cutting torch. For welding groove making, it can take the place of Triple Plate Cutting Machine and or Edge Milling Machine. So, the corresponding machine purchase budget and workshop land occupation can also be saved.
