Can fillet welds be fully penetrated? Please explain, experts!
Can fillet welds be fully penetrated? It’s not an absolute issue – sometimes they can be penetrated and sometimes they cannot; this mainly depends on the thickness of the base metal plate as well as the shape of the weld gap. When the base metal is thin, or when it is thick but a double V-shaped gap is used, full penetration is possible!!
2# liangj2009: Gas shielded welding – can two plates 20mm thick be welded together without beveling at the joints, and will full penetration be achieved?
It’s impossible to weld through. Whether full penetration can be achieved depends not only on the design intended for full penetration but also on the welding process and methods used.
Whether full penetration is achieved is related to the welding process, the welding method, the groove prepared by the designer, as well as the welder’s sense of responsibility
The groove of a welded joint is a key factor determining whether full penetration can be achieved. Without a groove, it is quite difficult to achieve full penetration even in 20mm thick plates, let alone in fillet welds, where defects related to lack of full penetration are also common.
It should be very difficult to achieve full penetration when welding something this thick without making a groove
Back to the third floor: It’s impossible to weld through; a groove needs to be made.

Fillet welds can be fully penetrated, provided that an appropriate notch is created and a suitable alignment gap is maintained; in other words, the design of the fillet weld joint must be based on the requirements for fully penetrated joints.
Whether full penetration can be achieved mainly depends on the groove shape! There are also the welder’s skills and technical capabilities ； It has a significant impact on welding processes!
