短弧焊
英文
short arc process-
Gmaw short - arc tack welds shall not be incorporated into the root pass
熔化極氣體保護焊-短弧點焊焊縫不能與根部焊道合成一體。Transitional feature of the arc and metal droplet in the welding process with steam shielded arc is investigated by means of analysing the waveforms of welding voltage and current under different welding regimes and it is found that there are two types of arc process behavor ? " arc starting - arc blowing out - short - circuiting " and " arc - starting - short - circuiting ". under the condition of constant diameter of welding wire and its feeding speed, the arc process behavor can be changed by adjusting the inductance of welding circuit as well as the voltage of power supply. if arc process behaves as alternative process of " arc starting - arc blowing out - short - circuiting " with minimum time duration of arc blowing out and maximum frequency of short - circuit transition, the welding process will be stable with less spatter and smooth weld bead
通過分析不同焊接規范下的焊接電壓和電流的波形.研究了水蒸氣保護下電弧及熔滴過渡的特點,發現其電弧過程行為有「燃弧?熄弧?短路」和「燃弧?短路」兩種形式.在焊絲直徑和送絲速度一定的情況下,通過調節焊接迴路中的電感量和電源電壓,可以改變電弧的過程行為形式.若電弧過程呈「燃弧?熄弧?短路」交替進行,並且熄弧時間最短時,短路過渡頻率最高,在這種情況下,飛濺小,焊道成型好,焊接過程穩定Randomicity amp; stability of short - circuiting droplet transfer in arc welding process
弧焊短路過渡過程的隨機性與穩定性The gmaw short - arc process shall not be used for welding socket welds or the root pass of o - lets and branch connections
熔化極氣體保護焊-短弧工藝不適用於承插焊接或出口和分支連接的根部焊道。Due to two work states - - - arc burning and short current - - - existed in welding process of consumable electrode welding, and different control objectives in these two states, two close - loop feedbacks are designed in the control system : welding voltage feedback and welding current change rate feedback
根據熔化極co2焊機具有燃弧和短路兩種工作狀態,且兩種狀態下控制目標不同的特點,在控制系統中設計了雙閉環反饋:焊接電壓反饋及焊接電流變化率di / dt反饋。In view of the external form of the roof construction, it was decided that the variant steel arched girder should be composed of a higher straddle and a lower straddle, with a stump welded between the two straddles. the straddles are two arc - shaped roofs of different curve rates, and each of the straddles is made up of segments of various curve rates
根據實際工程屋蓋建築的外形,確定變異鋼拱架分高跨和低跨部分,中間採用短柱焊接成一整體,高跨和低跨由兩個不同曲率的弧組成,且每一跨又有多個曲率。The co2 welding process needs the special external characteristic and dynamic characteristic of power source for there are alternately arcing time and short circuiting time at the period of short - circuiting co2 welding
在採用短路過渡方式的co2焊過程中,短路和燃弧過程交替發生,因此它對電源的外特性和動特性有特殊的要求。Selection modse of long / short weld, build - in remote control device, capable of ignition and cratering electric arc with small current
具有「長焊縫/短焊縫」選擇功能及遙控裝置,可進行小電流引弧,收弧。In this thesis, an arc sensor based on fuzzy control is designed. through the change of welding current in waving, the arc sensor judges the excursion and provides the adjusting output, meanwhile, it transmits the data acquired to a personal computer to be displayed and analyzed
本文介紹了短路過渡的co _ 2氣體保護焊電弧傳感器,通過對擺動過程中焊接電流的變化來判別焊縫偏移情況,採用模糊控制得到控制輸出,並將數據經串口通信傳送到pc機上加以顯示和分析。分享友人
