Welding machine to join ends of steel sheet rolls

You have some band gashing problems in your tool-kit ?
You want to improve your production capacity ?

We suggest you :

• A saving of time
• A matter gain
• The flexibility in your workshops

Our welding machine allows you to produce in continuous, whatever the strip dispensing process is, without having to stop the line, which eliminates the repeated feeding and starting operations. 

This equipment increases the feeding capacity of the presses, the extrusion machines or all the other production lines using rough strips. 

It is not necessary to stop the production cycle after the strip decoiler or the loop, even if you do not have an accumulator : the strip ends are joined with a welding process and the operations consisting in introducing the strip and starting again the cycle are not required any more. 

The ST120 welding machine can be installed between the strip decoiler and the accumulator . However, due to its flexibility, It can also be placed before the strip feeding system. 

Examples of applications : strip cutting and stamping, cold forming, feeding machines, trancanage , slitting line, frame extrusion machines, etc.

ST120 : the reference machine

Main characteristics :

• Welding TIG (without contribution of matter)
• All matters are welding
• Cut thickness is between 0,2 and 1,5 mm
• Width band is between 7mm and 110mm (>120mm, refer to us)
• Hydraulic source for the cut
• Dimensions : depth 1250mm - width 1000mm - heigth 1800mm
• Electric supply
• Pneumatic unit 6 bar
• Man/machine dialogue with touch panel
• Welding programs memorization
• Easy use

The ST 120 machine is realized with standard components already in industrial conditions.

The different operations :

	Band in the rough
	The two bands are cut with an angle of 15°.
	It's an essential stage to join the ends of band. With two linear motions, the two extremities are joined end to end
	The two extremities are welded
	After the welding, according to the matters and the asked welding charasteristic, the welding cord can be compressed; there isn't almost left any thickness

The process :

The welding machine use is easy because the touch panel will help you during the welding cycle.

• Preparation of the end ans start band extremities
• Band flanges
• Cut the welding band extremities with the cut tool-kit and by double cutting blades retraction in the matrix barrel
• Join the ends of the two bands and extremities placing on the rim welding
• Lower the welding arm
• Start the welding process. The torch lights up, start its translation motion and executes according to the programmed parameter
• At the cycle end, the welding arm with the torch go back their initial position
• Open the tightening pliers
• The operation is finished

As a rule of thumb, the cycle time is less than a minute, depending on the material and the operator.
