Discussion Overview
The discussion revolves around the challenges and methods of cold pressure welding, particularly focusing on joining two sheets of metal through lap joints. Participants explore various techniques, equipment, and applications related to cold welding, including practical experiences and theoretical insights.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
Main Points Raised
- A participant, a mechanical engineering student, shares their unsuccessful attempts at cold welding using simple methods like hammering and pressing with a vise, seeking advice on potential mistakes.
- Another participant questions the effectiveness of the methods used, suggesting that cold welding requires specific conditions that may not be met by the techniques mentioned.
- A seller of cold pressure welding equipment notes that their equipment is not suitable for sheet metal due to the high pressure required, but mentions its effectiveness on wires and rods, including welding aluminum to copper.
- One participant recalls seeing cold welding of aluminum sheets in aerospace applications, describing a method involving a rotating head that applies pressure while moving along the sheets.
- Another participant expresses surprise at the lack of information available online regarding cold welding of sheet metal, noting that many sources claim it is not feasible.
- A repeated comment mentions a method seen on a show, indicating that explosives were the only successful means of cold welding two sheets of metal.
Areas of Agreement / Disagreement
Participants express differing views on the feasibility and methods of cold welding sheet metal, with no consensus reached on the effectiveness of the techniques discussed or the conditions necessary for successful welding.
Contextual Notes
Some participants reference specific applications and methods that may not be universally applicable, highlighting the dependence on material types and welding conditions. There are unresolved questions regarding the technical requirements for successful cold welding of sheet metals.
