Glass welding two tubes together, Welding two glass tubes together. The tubes are made of lead glass and are used as filling tubes for neon lighting. The OD is 5mm and the ID is 3mm. The torch is a simple, handheld propane-torch, and the tubing is held right at the tip of the flame to avoid overheating the glass (which causes the lead to conglomerate at the surface, making the glass appear metallic). The welding is accomplished by heating the glass to red-hot while spinning the tubes to prevent cracking. Holding then at a slight angle, the edges are touched together and rotated to seal it together around the circumference. Then pressing to fatten the weld and pulling to thin the weld to the necessary 1 mm thickness, all while blowing slightly to maintain a tubular shape. This photo was taken the moment the two tubes touch., The welding together of two tubes made from lead glass

2本の管を一緒に溶接するガラス管を溶接する。管は鉛ガラスでできており、ネオン照明の充填管として使用される。ODは5mm、IDは3mmである。トーチはシンプルな手持ち式のプロパントーチで、チューブは火の先に保持され、ガラスが過熱しないようにする。溶接は、ガラスを回転させてガラスを赤く熱し、割れを防ぐために行う。わずかに角度を保って、縁を接合して回転させ、縁の周りに密閉する。次に、溶接部を太くし、必要な厚さ1mmの厚さに引っ張って溶接部を薄くする。この写真は、2つのチューブが触れる瞬間に撮影された。鉛ガラスで作られた2つのチューブの溶接。
