Mastering a velox ars unius, postesided welding et geminus postesque formatam

Nam manual arcus Welding 'unum, postesided welding duplex postesque formatam ' processus secundum modum operandi, potest dividitur in continua welding modum et intermittoscere arcus exstinguendo modum.

In low ipsum ferro et humilis stibio ferro Welding primum accumsan fere semper uti intermittoscere arcum welding. This welding method can use a larger current, with greater penetration, and can control the pool temperature and switch, can do the root weld through, while continuous welding method, that is, continuous welding without interrupting the arc must use a smaller welding current, the temperature is low at the start of welding, but after welding a section of the workpiece temperature rises, it is not easy to control the pool temperature and pool size, so it Difficile est ut radix per et non tumore, ita primum layer raro usus est. Ideo primum layer est raro solebat, sed ad secundam iacuit post welding.

Intermittent arc extinguishing method is mainly through the control of arc burning and arc extinguishing time, the use of reasonable transport bar action to control the melt pool temperature, melt pool time, melt pool switch and the thickness of the liquid metal layer, in order to obtain a good reverse formation and internal quality, but regardless of which welding method, the arc on the bevel melting degree, and is divided into penetration fill the gap between the butt. Ex superficies, quod est radix formatam, sed in essentia radix de LIMUS non realiter conflandum per quod non transiet contra faciem flectendo test, ita non est usus. Plerumque sunt ad consequi una-postesided welding duplex postesque formatam penetrat radix de Welding modum.

Single-postesided Welding duplex postesided formans modum operandi, pro carbonis ferro, humilis-alleo ferro aut immaculatam ferro welding, tum quod usus DC potentiae vel in sequentibus, non obstante sunt idem, maxime ad control sunt in sequentibus tribus rationibus.

I, radix gap coetus gap sit oportet

In causa autem rationabile angulus, oportet esse proprium radix gap ut ad scuttas virga traditur radix, ut arcus per septentrionalem partem, in radice. Ut facile consequi uniformis penetratio, generalis radix gap magnitudine deviationem esse circiter I mm.

Radix Gap mole debet esse equivalent ad diametri de welding virga solebat aut maius quam diameter 0,5 ~ 1.0 mm vel ita oportet.

Magnitudinem radix gap ad plures factores electus comprehensive consideratione.

① thickness of the workpiece, such as the weld is thin, heat dissipation is slow, the weld heat is not easy to dissipate, the root gap can be smaller, thicker weld should be appropriate larger, in order to facilitate the root penetration.

② processus parametri, welding current est parvum, radix gap sit leviter maior, cum welder adhibetur ut usura a maius current operationem, radix ad usura a maius current operationem, radix est ad reduciendum est.

③welding situ, radix gap de flatam et horizontalem non esse minor, dum tergo rima et verticali ad leviter maius.

④BLunt Edge Size: Si blunt ore est magnum, radix gap etiam esse maior.

⑤ WELDING ordo, radix gap debet esse conflatum primum, radix gap debet esse non debeat si ad magnum, praeter considerare thermal expansion et aliis.

II, quod angulus debet esse oportet, et habere aliquam magnitudinem obtusum in ore gladii.

Bevel angulus debet esse secundum 'praecepta ' et technica conditionibus consilio ad angulum anguli directe afficit qualitas iuncturam et magnitudinem, ut v LX ° ~ ~ ~ ~ LX ° ~.

Bluntum ripam per crassitiem partem directionem finis bevel non aperire. Secundum crassitudine workpiece est plerumque relicto cum 0.5 ~ 2.0 mm magnitudinem obtusum obstupuerunt. Ut murum crassitudine III mm, quod blunt in ore sit 0.5 mm, ut murum crassitudine XII mm vel magis, ut sit 1.5 mm, quod est maximum non excedat II mm est, ad blend est per. Nimis facile pupugerunt magna conflandum foraminis.

Cum blunt ore arcum post arcus preheat workpiece diutius praeehoing range potest esse maior, ita improvidus in processus conditionibus crescente mobilitate liquido metallo, facile ut pergant.

Cum blunt ore, potest resistere maius welding excursus et non penetrare radix simul arcum inducitur. Cum enim blunt ore est facile ad imperium in mole ad conflandum stagnum, quod est conducere ad radicem penetrationem. Maxime in supina welding situ, paulo altius current debet electus ad agunt, aliter non solum impossibile est formare sed etiam difficile superare processus defectus ut poros et siring. Ergo quaedam magnitudo obtusum est ipsum necessarium.

III, usum penetrationis welding modum.

Breakthrough Welding modum, hoc est, in in Welding processus, penetrans vim ducens arcus, liquescens penetrare radix ut radix, ut per formationem per formationem.

The specific method of operation is: after the arc is triggered, the arc is stretched to preheat (flat welding preheat time is short, not very obvious, the position of the weld is very obvious), when the state of semi-melting (ie, in the welding goggles to see the bevel edge of the preheated 'sweat beads' when about 3 to 4 seconds), the arc is depressed, melting penetration blunt edge, so Quod speciem paulo maior quam gap inter buttress 'Foramen ' ita ensuring quod pars deposita metallum transitus ad radix et retro ad fusum et conflatile basi materiae simul ad formare fusilia.

Sicut in electrode continues ad conflandum, penetratio ad conflandum foraminis est aegre, in hoc tempore ad oportet arcus exstinguendo ars, ut refrigeretur ad formare weld. Tum ledo iterum, liquefacing blunt ore, et formare et fusilia fusilia, et tunc weld in hoc saepius ad consequi a tergo de Clendation.

Formatio fusilia est quod radix est per. Magnitudinem ad conflandum foraminis mole, id est, in magnitudinem marcam retro weld. Plerumque control diametrum ad conflandum foraminis ad blandeque gap circiter 1.1 ad 1.5 temporibus. Imprimis magnitudine secundum workpiece crassitudine, Welding situ, specificationem parametri et radix alvi, ferro et aliis factores ad adjust. Plerumque, processus test peragitur primum et lex instar ex ante welding ut qualitas welding.

After the second layer of welding using continuous welding method, pay attention to reduce process defects, welding current to moderate, for carbon steel and low-alloy steel weldments, after welding to control the slow cooling, to obtain good organizational properties of the joint and create conditions for gas escape, for austenitic stainless steel weldments, it is required to choose a smaller welding process specifications, after welding natural cooling or make it fast Refrigerant, ne tendentia ad producendum intergranular corrosio ex overheating.

Operculum layer (confirma welding layer) Welding, si prius sit 'filler ', ut in cibum altitudinis consistent, et non magis quam ad adjust in altum, ut adveniat, ad consequi speciem, ut consequi speciem.
