Evaluation of quality welds on chains for harvester
Teuer, Tomáš ; Kubíček, Jaroslav (referee) ; Sigmund, Marian (advisor)
The diploma thesis examines the influence of setting welding parameters and welding process on the resulting structure and strength of the welded joint of harvester chains. The theoretical part discusses the problem of weldability of pine steels by using method “135” with the possibility of destructive or non-destructive testing of welded joints. In the practical part, this matter is examined on a specific weldment, the harvester chain. Cross member with a cube welded in two ways by method 135, followed by an assessment of the performance of welds. The results of the evaluation are written down in the manual.
Qualification of welding procedure for cobalt plus heat-resistant stainless steel alloys
Teuer, Tomáš ; Kubíček, Jaroslav (referee) ; Sigmund, Marian (advisor)
This thesis deals with the welding of heterogeneous materials, namely cobalt and heat-resistant stainless steel alloys refractory GTAW (WIG). The main objective is to develop a preliminary specification of the pWPS welding procedure for a particular component and its subsequent qualification of the WPQR welding process. Furthermore it is necessary to set requirements of mechanical testing and differences for qualification requirements according to EN ISO 15613 for this welding component.
