Recently, consider suchlike problem, used resemble the sort of shown in Fig. 4 A at copper pipe (a) the point plating iron and the electric soldering iron tip of other part chromium plating outside this conical tip portion.But this soldering tip has following shortcoming: be difficult to even formation as the coat of metal, copper pipe is subjected to the high temperature heating during owing to weld job, and the coat of metal is easy to sustain damage, and conical tip portion can not effectively stop the caused corrosion of welding etc.

In addition, though shown in Fig. 4 B, disclose the most advanced and sophisticated head of the copper pipe material after the machining (c) is inserted the inner jack (b) of the soldering tip body (a) of aluminum material, goes up the electric soldering iron tip of plating palladium (d) at the most advanced and sophisticated head of the soldering tip body (a) of aluminum material, but it must cut, process the most advanced and sophisticated head (c) of making the copper pipe material with method for distinguishing, and must press most advanced and sophisticated head (c) and be inserted in the jack (b), so the difficulty of making, the production cost height.And, owing to be transmitted to of aluminum material soldering tip body (a) the at short notice outwards heat release of the inner heat of jack (b) by the heat insulating ability difference, thereby when large-scale welding thing is carried out weld job, the temperature that generation has been passed to operation thing self because of the heat of soldering tip descends, and causes problems such as lead can not dissolve.

The objective of the invention is to find out above-mentioned prior art problems point, provide be easy to make, low production cost, be specially adapted to carry out the electric soldering iron tip of complexity, accurate weld job.

According to electric soldering iron tip provided by the invention, end at copper pipe forms end difference, the intercalation of the tip of firm material on the excircle of this end difference, after treating to insert this copper pipe in the soldering tip body of hollow shape, for most advanced and sophisticated head is engaged each other closely with the soldering tip body, suitable shape is processed in the end of the soldering tip of the end difference that comprises the most advanced and sophisticated head of intercalation with Forging Technology.

When forging the end of process welding head, vertically come off from copper pipe in order to prevent most advanced and sophisticated head, also special vertical inner edge at the copper pipe end difference that contacts with most advanced and sophisticated head provides weld part.

Electric soldering iron tip of the present invention does not need to make most advanced and sophisticated head with other method during fabrication, owing to can use the normalization copper pipe, through once forging operation, most advanced and sophisticated head just closely engages with the soldering tip body is firm, so be easy to make low production cost.In addition, if compare more durable economy with the product that forms the coat of metal.

If,, thereby can prevent that the soldering tip body is stained with lead because lead only is bonded at the end of most advanced and sophisticated head when carrying out weld job particularly with manufacturing soldering tip bodies such as stainless steel materials; The heat of copper pipe is conducted by stainless steel soldering tip body extremely efficient in preserving heat in addition, so both made the weld job thing very big, the heat of soldering tip also non-conducting arrives the weld job thing, thereby comparatively desirable.

The most advanced and sophisticated head of soldering tip wishes to use firm ferrous material or ferroalloy.
