What else can I help you with?
What would you do when you see a fellow welder fell unconscious while welding in a confined space?
Should rescue, apply emergency Procedure and call an ambulance.
What type of welding makes the most money?
Space Welding. Yes they have welders in space!
What would you do when you see a fellow welder fell unconcious while welding in a confined space?
If I saw a fellow welder unconscious in a confined space, I would immediately call for emergency assistance and ensure that the area is safe to enter. I would activate the emergency shut-off for any equipment and, if trained, attempt to assess their condition while keeping them as stable as possible. I'd also notify any nearby coworkers to assist and prepare for the rescue team’s arrival. Ensuring proper ventilation and safety measures would be crucial to prevent further incidents.
Management of welding materials in space frame company?
Acceptance of welding materials The quality of welding materials must meet relevant standards. Before the welding materials are put into the warehouse, the warehouse management shall first verify whether the following relevant materials are complete, otherwise they shall not be put into the warehouse, and the materials shall be properly kept for future reference. ①Qualification certificate of welding materials ② Brand and mark of welding materials ③Batch number, specification and quantity of welding materials The material manager is responsible for the appearance inspection and re-inspection of the welding materials, and the unqualified products shall not be put into the warehouse. Storage of welding materials The storage of welding materials is mainly to prevent the corrosion of the welding wire and the steel core of the welding rod, and to prevent the coating of the welding rod as well from being damp, deteriorated, or even falling off, thus affecting normal use. The drying of the normally stored welding rod, welding tip, flux and flux-cored wire before use is an important part of welding quality management. 1.The space frame company that uses welding rods should set up a special welding material warehouse. The welding rods, welding wires, fluxes and welding tips should be stored in a dry, well-ventilated place and kept by a dedicated person. 2.Thermometers and dehumidifiers should be installed in the welding material warehouse. The indoor temperature should not be lower than 5℃, the relative humidity should not be higher than 60℃, and the ventilation should be good. 3.Dedicated drying box and constant temperature box should be installed in the warehouse. 4.Eye-catching baking specifications should be hung in the warehouse, and management personnel should strictly follow the specifications 5.Welding management personnel shall establish accounts and mark the cards according to classification, brand number, specification, and batch number, and ensure that the accounts, cards, and objects are consistent. 6.Welding materials must not be stacked on the spot, and should be more than 20 mm away from the ground and 300 mm away from the wall 7.Special attention should be paid to the environmental humidity in the storage of welding rods 8.The higher the relative humidity and temperature in the air, the higher the partial pressure of water vapor, and the easier it is for the skin to absorb moisture. It is generally recommended that the relative humidity in the air be less than 60%, and a certain distance (about 20 cm) away from the ground and walls. The temperature is preferably 10 to 25°C. 9.The drying temperature of low-hydrogen electrode should be 350-380℃, and the holding time should be 1.5-2h. After drying, it should be slowly cooled and placed in an incubator at 110-120℃ for storage and use; In the insulation cylinder; if the dried low-hydrogen electrode is placed in the atmosphere for more than 4 hours, it should be re-dried; the number of repeated drying of the electrode cannot exceed twice; the damp electrode cannot be used. 10.Welding rods, welding tips, fluxes and flux-cored welding wires must be dried in accordance with the product manual and relevant process documents before use. 11.The heating, temperature measurement and temperature control performance of the welding rod, flux drying device and heat preservation device should meet the requirements of use. 12.Distinguish the type and specification of the electrode, and it can't be misused. 13.In the process of welding rod transportation and the other party, always pay attention not to damage the coating and the other party should not be too high. We should be more careful about welding rods with poor coating strength.
What tack welding size and spacing is needed in relationship to material thickness?
If tack welding is just for the purpose of holding the part in place then the welding tack size should be enough to hold it in place and should not exceed the final welding size. Spacing and number of tacks can vary depending on your requirement, but if enough space is available then try to avoid the consecutive tacks in the heat affected zone area of the previous welded tack. Usually spacing of 25 to 30mm is enough, increase the spacing as there is an increase in the leg size of the tack weld.
How do you weld in outer space?
It is possible by using ultrasound as well as electrical arc welding.
Whenever workers will perform hot riveting welding cutting or burning or heating operations within a confined space they will obtain an?
AF Form 592, USAF Welding, Cutting, and Brazing Permit
How many cfm are minimum required for welding in a confined space without respirator protection?
2200 cfm
What is the deepest a man can weld under water?
In a pressurized diving suit the limitations will be the maximum depth the suit can withstand; since the deepest dives are accomplished in full "space suit" like outfits. The overall depth of welding may be unlimited through the use of robotic arms on Deep Submersible Vehicles equipped with welding gear. There are different types of welding in which special gas displaces the ordinary atmosphere in the immediate area the weld is taking place. So, in order to accomplish a weld a extreme depths the Welder would need to transport not only themselves, but the necessary welding rods and special gas cylinders. All these factors begin making fabrication at the surface more economical and practical, with the final structures submerged to "the bottom" and assembled in place.
Why does 2 bits metal weld together in outer space?
In space, there is no atmosphere to interfere with the welding process, so the two metal pieces can bond directly without oxidation or contamination. Additionally, the lack of gravity allows for a more even distribution of heat during welding, resulting in a stronger bond between the metals.
Can you weld in outer space?
Yes, you could. When we weld, we use several different techniques. They will work out there in space. For instance, if you have an electric welder, it will still pour out a bunch of electric current when an arc is struck. The arc and the following current will create the molten metal "pool" at the site of the electrode and the work just like on earth, and you can create a bead. But you won't have to worry about the effects of air on your weld. No flux will be required to prepare or keep your material clean. Certainly if we wanted to trouble ourselves to haul up welding gas to weld, we could do that, too.
What are the enviornments of welding?
The environments of welding could be one of the following:- open air- outer space- under waterthese different environments need different energy sources like gas flame, an electric arc, gas flame or laser.
