Dear All,

We are now facing Lack of Fusion issues with Narrow Groove GMAW (Mechanized Welding). Material is API 5L Grade X60/65. Pipes are having some hi-lo issues too (around 2.5 mm). If anybody came across a similar scenario, kindly share your experience and the way you tackled it.

Thanks and regards,

Hari
