In the prior art, the welding and the assembly of the non-detachable condenser liquid storage dryer are completed by two devices, and the welding and the assembly need to be completed by two persons every time, so that the production efficiency is low. In addition, for the sealing welding of the liquid storage dryer, two popular welding methods are flame welding and manual MIG (metal inert gas) welding. However, both of these methods have significant drawbacks:

1. flame welding is very high to the demand of non-metallic part apart from the welding seam in the liquid storage tank, and the distance will burn out inside working of plastics, causes the part to scrap. Under the low cost and light weight and trend of the existing condenser, most condensers cannot meet the distance requirement when designing a liquid storage dryer, and cannot be compatible with the current and future product trends;

2. because this welding seam has strict leakproofness and withstand voltage requirement, has very high requirement to welding quality and stability during MIG welding, and artifical MIG welding can't be in batches and continuously guarantee higher welding quality under high strength operation in a large number, can cause some product welding to have the gas pocket, mix with and welding seam offset scheduling problem, leaks to cause in the back process and scrap or the product durability descends and the quality problem appears in the customer end.
