S&T: Deposit welding Robot is commissioned at SFRE

Deposit welding Robot is commissioned at SFRE

CISDI teams have created a robot capable of high-quality deposit welding.

During pilot tests, the robot was able to perform surface deposit welding on wedges, guides and support sleeves.

It has now been handed over to SFRE and is in commission in one of its workshops, where the robot’s welds are so reliable, no defects have been detected by the surface flaw inspector.

Copper surface deposit welding prevails at SFRE. However, it’s a dangerous task; high-heat toxic gas, metal steam and metal dust are generated which are dangerous to workers’ health. Producing welds of consistent quality also requires a high level of skill and labour and procedure-transfer costs can be high.

The Robot can complete non-standard copper deposit welding at one duty position and reduces manpower.

CISDI will transplant the knowledge it has gained into other metallurgical robot developments.

Deposit welding robot fact file:

Applicable for non-standard copper deposit welding in a single piece and in small batches, with diverse varieties and without clamps, and also for the automatic deposit welding of carbon steel and stainless steel

Stable and reliable quality

Gives a high degree of flexibility. The robot can be adapted for various shapes of surface deposit welding and for non-standard, clamp-free and positioning-free pieces

Easy training – no need for repeat programming

Much less labour-intensive

Can be programmed offline

Capable of deposit welding on curves in a complicated space
