Welding cables should never be tied to scaffolding or ladders because doing so can create a serious safety hazard. This practice risks damaging the cables, which can lead to electrical shorts or fires. Additionally, tying cables to scaffolding or ladders can create tripping hazards for workers, increasing the likelihood of accidents. Proper cable management is essential to ensure a safe working environment.

What is the process of underwater welding?
Underwater welding uses a special flux around the welding rod which produces gasses which form a bubble around the end of the rod ,excluding the water. It is difficult and never as strong, lacking penetration. It is only used when absolutly necessary.
What is the difference between fusion welding an resistance welding?
Fusion welding is just any welding process which inhibites the phase trasition from solid to liquid and then back to solid state, while electric resistance welding is based on purely ohmic heating of the different parts, this heat will create fusion of the metal. So; Electric resistance welding can be said to be a type of fusion welding, but not the other way around.
For rebar that is embedded in a poured slab or in a sprayed concrete wall when is welding required and when will using twisted wire suffice Can you include a link to the standard Thnx.?
Tie wire should be used always, not welding. Rebar integrety is comprimised when welded. A specific grade of rebar, A706, exists for welding but otherwise, its is not advised that rebar be welded. See below:Q: When is it appropriate to use welded splices in the field? A: The ACI 318 Building Code requires the architect/engineer to indicate the type and location of welded splices of reinforcing bars on the project drawings or in the project specifications. The ACI 318 Building Code further requires that all welded splices should conform to the Structural Welding Code for Reinforcing Steel published by the American Welding Society, which requires the project contractor to prepare written welding procedure specifications (WPS) for all welded splices. These will depend heavily on the assessment of carbon-equivalent (CE) and other rebar properties as determined by the mill test reports that accompany each shipment. For more information about welding reinforcing steel, see the American Welding Society's (AWS)Structural Welding Code for Reinforcing Steel.Q: Can tack welding be used to hold reinforcing bars during assembly? A: Field tack welding should never be used as a substitute for tying in assembling and securing reinforcing bars. Rare exceptions are specified in the International Building Code.Source link: http://www.crsi.org/contractors/faqs.html
What kind of welding rod do you use to weld railway lines?
E7018---- I'm adding this to the answer. Never having welded rail I have seen a video of one process. It is called Thermite Welding. A mold or dam is built around the joint where rail ends meet. A mixture of Aluminum Oxide and iron powder is poured into the mold and ignited. The mixture burns at a very high temperature melting the iron powder and the ends of the rails. After cooling the slag is hammered off and the extra weld metal is ground to the shape of the rail. Google Thermite welding. A video is available.
Does metalcore welding wire need shielding gas?
Yes it does. Metal Core wire doesn't have flux in his core, but powder metal. The powder metal doesn't have addition of "gas producing elements" to protect the weld puddle from ambient atmosphere. Your wire supplier will help you in the selection of proper shielding gas. But never forget they are "sellers" before everything. Don't be foul.
What should you never wear when welding?
A bikini
Which of the processes joins metals plasticaliy in welding?
The solid-state welding processes. This can include friction and friction stir welding where the base metal never reaches its melting point.
What safety measures should be taken when using scaffolding walk boards on a construction site?
When using scaffolding walk boards on a construction site, it is important to follow safety measures such as wearing proper protective gear, ensuring the walk boards are secure and stable, using guardrails and toe boards, and inspecting the scaffolding regularly for any damage or defects. Additionally, workers should be trained on how to safely use the scaffolding and should never overload it with excessive weight.

Why do birds never get killed when they sit on electricity cables?
i belive it because there not grounded ?
How many step ladders are there in the world?
As there has never been a world step ladder census, we do not know for certain. But we can safely say there are millions in existence.
Industrial applications on welding using ultrasonicswaves?
those packages that electronics are in that you can never get open--those are ultrasonically welded
Is a firewire cable a standard component with most new computers?
No. Communication cables, printer cables and other cables have never been a standard component of computers. This is because the cable is specific to the device you will connect to the computer. The only standard cable is the power cable.
Is it safe to use jumper cables with wires showing?
Never use cables with wires exposed. The wires can ground to the vehicle, start a fire or worse case, electrocute you to death. There is enough current going through the cables during cranking to weld steel(100+amps).
What type of welding process is used in outer space?
i think it's use arc welding without gas,,. hm hmm,,. I'm just think that b'coz,,. there's no air and little gravity (there's never be ZERO gravity believe me),,.
What is the difference between fusion welding an resistance welding?

So; Electric resistance welding can be said to be a type of fusion welding, but not the other way around.
What is the colour of oxygen cylinder in welding?
It is usually green, but owner-bottles (those not owned and rented out by a welding company) can be any color. There should always be a label on all cylinders identifying the contents. Never go just by color.
