Since there is a problem that metal components will elute and holes will open in the metal,
In many cases, resin or glass that has been line-rung processed inside is used. In addition to the acid, it may be stored in a lined container for the purpose of keeping the chemical solution clean to some extent.

The welding rod of the present invention can be applied to any type of resin as long as it is a thermoplastic resin such as polyvinyl chloride, polyethylene, polypropylene and fluororesin. In particular, it is preferable to use a fluororesin which is excellent as a corrosion resistant lining material. The reason for this is that when a fluororesin is used for the lining sheet, welding defects are likely to appear with welding rods having the shapes shown in FIGS. 6 to 9, but if the welding rod of the present invention is used, welding defects will occur. This is because it can be prevented. Further, when the welding rod of the present invention is used, welding defects are unlikely to appear even if the width of the groove to be welded is slightly narrow or wide.
