Lo­cal com­pany achieves ex­cep­tional weld­ing re­sults with Kemppi FastMig X Black

DEMM Engineering & Manufacturing - - NEWS -

Clarke En­gi­neer­ing Ltd re­cently achieved a weld­ing re­sult that one would as­sume was done robot­i­cally rather than by hu­man hands, thanks to the use of smart weld­ing equip­ment from Kemppi.

Based in Tau­ranga, Clarke En­gi­neer­ing spe­cialises in heavy equip­ment re­pair and main­te­nance, in­clud­ing truck bod­ies. Ac­cord­ing to the com­pany’s founder, Bruce Clarke, the com­pany reg­u­larly per­forms weld­ing tasks on heavy ve­hi­cles and al­ways has an eye on new weld­ing equip­ment that ap­pears in the mar­ket­place.

“In this case we were af­ter weld­ing equip­ment that would al­low us to join 14mm plates to the body of a 60 tonne trailer in one long, con­tin­u­ous weld. We did some re­search and iden­ti­fied a num­ber of op­tions for such butt weld­ing, but we were par­tic­u­larly im­pressed with the Kemppi FastMig X Black,” said Clarke.

Niki Bohlmann from Weld­ing En­gi­neers Ltd demon­strated the FastMig X Black for Bruce and his team. The Kemppi FastMig X Black of­fers high qual­ity MIG/MAG pulse weld­ing. It is per­fect for high qual­ity pipe weld­ing, and plate and root weld­ing from one side with­out back­ing. The FastMig X Black also of­fers di­verse weld­ing. It can be used to weld high strength steel and spe­cial al­loys as well as alu­minum.

“What im­pressed us the most about this ma­chine is the fact that you can se­lect your own set­tings for the task at hand. Plus it has enor­mous ca­pa­bil­ity and ver­sa­til­ity which means you can use it for var­i­ous weld­ing tasks,” said Clarke.

To weld the 14mm plates to the trailer trans­porter, Clarke used the Kemppi FastMig X Black’s pulse func­tion. “The pulse func­tion al­lowed us to weld at a con­stant, spe­cific pace with­out burn­ing through the me­tal. We teamed the FastMig X Black up with the Ko­belco MX-A70C6LF 1.2mm met­al­core wire and then set the fre­quency and am­pli­tude to the level we re­quired. The re­sults were out­stand­ing. The look and pen­e­tra­tion of the welds are stun­ning,” ex­plained Clarke.

“I doubt that we would have achieved sim­i­lar re­sults with a dif­fer­ent ma­chine. The Kemppi FastMig X Black’s ver­sa­til­ity to­gether with the WiseFu­sion func­tion pro­vides the welder with real choice so that a qual­ity re­sult can be achieved,” he added.

Ac­cord­ing to Clarke, the com­pany has also ex­pe­ri­enced in­creased lev­els of pro­duc­tiv­ity since pur­chas­ing the ma­chine. “When we com­bine premium grade wire with the FastMig X Black there is lit­tle need for re­work, which means we can get through our weld­ing jobs far quicker to ac­com­plish more,” he said.
