Dear sir,
We are Thai and being on the process of long arm construction for backhoe 322B, 9 metres long. There are 3 plates joining together at the moment, those are 1 base plate and 2 vertical side plates. 2 vertical side plates will be welded to the base plate inside and outside after that the 4th cover plate will be joined on top. The status is coming to the welding procedure. We are not sure whether welding can be done continuously on the inside and outside or what should be the right method on welding. Materials are St52 plate.
Thank you.
