Laser cladding the flanks of mill roll grooves. Published in 2018 By GA Kent, A Kilpatrick, M Eiteneuer, RI Letizia, N Alam TO REDUCE THE costs of maintaining mill roll shells, efforts have been made to extend roll shell life and to maintain the roughness of the tips of roll grooves through a season without the need for roll arcing.
This paper reports on the development of a coating to protect the lower flanks and root of the roll grooves. As part of the development, a change to SG iron as a roll shell material is recommended. Plasma transfer arc welding, metal inert gas welding and laser cladding techniques were developed, with laser cladding being the preferred methodology.
Drive rolls are essential to wire feed welding because the drive rolls are used to feed the consumable wire to make welds. There are 3 main different types of drive rolls to suit different wire types: 1. V Groove Drive Roll : for hard solid wires: steel, stainless steel. Provides good grip without damaging the copper coating on solid steel wires.

V Groove Feed Roll Are used for hard wires such as steel, stainless steel where the wire shape is not deformed due to tensioner pressure. U Groove Feed Roll Are used for soft wires such as aluminium. This type of wire can easily deform its shape making poor current pick up at the contact tip. Knurled Feed Roll Are used on tubular cored wires which are easily deformed.

The crack generally is directed down into the base metal, right at the weld toe. If you don't create a smooth transition of weld metal to base metal, you can disrupt the flow of forces through the weld. Such a high volume of weld metal creates significant shrinkage forces. When these forces exceed the strength of the weld, cracking ensues.

CHOOSING THE RIGHT DRIVE ROLL The three types of drive rolls most commonly used for wire welding processes are V-knurled, V-groove and U-groove. V-knurled drive rolls are used with gas- and self-shielded flux-cored and metal-cored wires that are softer due to the flux inside and the tubular design.
Elastic deformation of the mill takes place. If stiffer rolls are used, namely roll material of high stiffness or elastic constant, then mill spring can be avoided. ... It can also occur in down-hand welding with a backing strip at the root of the weld groove if slag is trapped between the molten metal and the backing strip.

2. Three-High Rolling Mills: In this mill, the three rolls stand in parallel one by others. The rolls are rotating in opposite directions. In this mill, between the first and the second rolls, the material passes. If the second roll rotates in a direction then the bottom roll rotates in another direction.

The roll forming mill is used for pipe diameters upto 600 mm maximum. It normally consists of 8 to 10 largely driven roll forming stands in which the strip is gradually shaped in stages (1 to 7 stands) into an open seam pipe. The last three passes (8-10 stands) are usually finish passes which guide the open seam pipe towards the welding table (11).

1) Increase the groove friction when changing rolls and grooves. Grind the grooves with a grinder or use spot welding, and turn off the cooling water of the rolls until they are completely bitten. 2) Check whether the guide base is loose and whether the wire rod rolling line is centered, and replace the old guide in time.
