Welding coupling tubes - カップリングチューブの溶接

Sometimes I weld coupling tubes for touring bikes. Coupling system is convenient to carry a bike because it can be separate in the middle of the tube. But, welding this coupling parts is more difficult than welding frames in a way. There is a reason. The welding bead must be straight (round). It means I have to weld perfectly straight. It is more difficult than you think. Obviously, it shows the welder's skill. You cannot make it clean unless you have had enough "basic practice". Welding coupling tubes requires the welder's skill because of its simpleness.
