TUBULAR WIRE WELDING WITHOUT GAS with Gala Mig 4007

Welding in carbon steels with standard solid wire in protected atmosphere. Welding in inner angle These wires are welding in opposite polarity to the rest of the MIG-MAG welding. In this case the polarity of the gun is negative and the mass is positive, and the slag is eliminated as if it were an electrode. […]

welcome students this is the seventh lecture on the gas metal arc welding process and we will see the different principles related to the gas metal arc welding process the power systems which are used in filler metals which are used in this process and the importance of the welding process parameters on production of […]

Can You Melt Obsidian and Cast a Sword?

Over the past few months I’ve been working on this video as a follow-up to user comments on a previous video on if it’s possible to cast obsidian. This proved to be a major challenge that took six attempts, broke multiple crucibles and two different kilns. But I didn’t want to stop until I finally […]

Gaining skills for a better life | Sustainability at Shell

South of Manila, in the Philippines, Brenda Aniyahan seemed destined to a life struggling to make ends meet, just like many underprivileged Filipinos do today. But she found a way to break the mould, and train for a job which set her apart from most women in her community. Brenda was lucky an opportunity opened […]

From the Workshop: Gas supplies

If you’re like me you’ve probably looked at your oxyacetylene bottles or argon for your TIG or argo-shield for your MIG welder and thought about the amount of rent on those bottles, let alone the cost to fill them up when they are empty. And you’ve probably thought “how much is that actually costing me […]

How to make a mini Hydrogen Generator / TUTORIAL

您需要準備這些東西 2個同尺寸的冰棒棍 在棍面上畫上鑽孔點 再叧一根棍面上重做一次 再穩穩的將兩根冰棍壓緊 鑽孔 鑽孔後就像這樣 每相隔一個孔鎖上一個螺絲並穿過兩冰棍 再換面重做一次 再螺面上焊上錫點(可視螺絲材質選用合適的錫) 換面重做一次 然後 再螺面錫點上焊上電線 現在 可以將導電模組放入玻璃瓶中 瓶蓋上要鑽一個合適孔徑的洞 拿出西藥房買的滴管組 切掉上端 將電線穿過瓶蓋開孔 再將滴管組的觀察室塞進孔中,盡量塞緊 再用熱融膠封口,確保氣體不外洩 鎖緊瓶蓋 再依據實際需求剪截滴管 在集氣瓶鑽2個合適大小的孔 將滴管末端由孔1塞入瓶中 一定要將管子穿到瓶底 再將裁剩的那截滴管由孔2穿入瓶內.不必穿太深 再以熱融膠封口 這時 可以倒入清水了 蓋上瓶蓋 取一些鹽加水攪均 再打開瓶1 (導電模組) 倒入剛才自製的鹽水(導電液) 要淹滿整個導電模組 鎖緊瓶蓋 現在可以將電線接上電源供應器了 調整輸出電壓為 2.1 伏特 現在 您會看到瓶內開始有汽泡產生 (泡泡測試)

How Plasma Cutting Works: Part 1

Plasma arc cutting is a process that uses an electric arc and high-velocity gas or air to cut metal. When gas or air is highly heated, it ionizes, becoming electrically charged plasma capable of conducting electrical current.
