RGT changes our understanding of narrow gap welding

RGT改變(bian)了小黄瓜a视频在线對窄間隙焊接的理解(jie)

In narrow gap welding, the groove angle is typically less than 20 degrees instead of the normal 45 to 60 degrees. This decreases the number of weld passes needed to complete the joint, and it reduces the welding time and the consumption of filler material. It also makes the material less prone to distortion. In other words, reducing the groove volume has a multitude of positive effects on welding quality, efficiency and productivity.

在窄間隙焊接中(zhong)，坡(po)口角度通常小於20度(du)，而不是通(tong)常(chang)的45到(dao)60度。這減少了完成接頭所需的焊道數量(liang)，減少(shao)了焊接時(shi)間和填(tian)充(chong)材料(liao)的消(xiao)耗(hao)。它也(ye)使材料不易(yi)變形(xing)。換言(yan)之，減小坡口(kou)體積(ji)對焊接質量、效率和生產率有許多積極(ji)的影(ying)響。

However, reducing the groove angle also brings more challenges to welding. In a narrow groove, the welding arc is difficult to control. This may result in quality issues, unless you invest in welding torch and accessories that are specially designed for the application.

然(ran)而，減小坡口角度也給(gei)焊接帶(dai)來了更多的挑戰(zhan)。在(zai)間隙坡口內，焊接電弧難(nan)以控(kong)製。這(zhe)可能(neng)導致(zhi)質(zhi)量問(wen)題(ti)，除非(fei)您(nin)投資於專門為應用設計的焊槍(qiang)和附件。

For narrow gap MIG/MAG applications with material thickness below 30 mm, Kemppi's Reduced Gap Technology (RGT) is an ideal new solution. It allows using standard welding equipment and welding application software for narrow gap welding of butt joints and fillet joints. The RGT solution combines the benefits of Wise application software, FastMig or X8 MIG Welder equipment, and A5 MIG Rail System 2500 welding mechanization system.

對於材料厚度低於30 mm的窄間隙MIG/MAG應用，Kemppi的縮小間隙技術（RGT）是(shi)一種理想(xiang)的新解決方案。它允許使用標(biao)準(zhun)焊接設備和焊接應用軟件(jian)進(jin)行(xing)對接接頭和角接接頭的窄間隙焊接。RGT解決方案結合了WISE應用軟(ruan)件、FASTMIG或X8 MIG焊機設備和A5 MIG軌(gui)道(dao)係統2500焊接機械化係(xi)統的優(you)點。

A control system ensures consistent power and precisely focused arc

控製係統確(que)保(bao)穩定(ding)的功率和精確的聚焦電弧。

At the core of Kemppi's RGT solution is the most advanced arc control system available, which delivers consistent arc power at contact-tip-to-work distances of up to about 30 mm. In addition, the system adaptively adjusts the arc to keep its energy density at the maximum level (see Figure 1). A short, stable, and efficient arc minimizes the risk of incomplete penetration and lack of fusion, because the arc is always focused precisely at the desired point in the groove. The RGT control system enables reliable narrow gap welding of materials with thicknesses up to 30 mm, without the need for special equipment or accessories.

Kemppi的RGT解決方(fang)案的核(he)心是最(zui)先進的電弧控製係統，使得導電嘴(zui)到工作(zuo)最大距(ju)離接近(jin)30mm的情況(kuang)下，依(yi)然能夠(gou)提供了一致的電弧力(li)量。此外(wai)，係統自(zi)適(shi)應調整(zheng)電弧，使其(qi)能量密(mi)度保持(chi)在最大水平(ping)（見(jian)圖1）。短、穩(wen)定和有效的電弧可將(jiang)未焊透(tou)和未熔(rong)合的風險降至最低(di)，因為電弧總是精確聚焦(jiao)在坡口中所需的點(dian)上(shang)。RGT控製係統能夠可靠地對(dui)厚度達(da)30 mm的材料進行窄間隙焊接，無需特殊設備或(huo)附(fu)件。

Figure 1. The principle of the RGT control system is that WisePenetration maintains consistent arc power regardless of variation in the contact-tip-to-work distance while WiseFusion provides adaptive regulation that keeps the arc focused and optimally short.

Savings potential illustrated by a preliminary WPS

初(chu)步WPS說明(ming)節約的潛(qian)力

Kemppi’s RGT narrow gap welding solution has produced good results with a 20° groove angle and material thickness of up to 30 mm. The pWPS shown in Figure 2 is approved via tests in compliance with the standard on welding procedure qualification testing. It provides all the information required for the utilization of Kemppi's narrow gap solution in production welding. It was created for a butt joint with a 20° groove angle and a thickness of 25 mm. Figure 3 shows a calculation of the savings potential that the method yields. The smaller, 20° groove angle will result in a groove volume about 25% lower than with a 45° groove angle.

Arctech Helsinki Shipyard uses Kemppi's technology

赫(he)爾辛基ARCTECH造(zao)船廠采用KEMPI的技術

Among the users of Kemppi's RGT narrow gap welding solution is Arctech Helsinki Shipyard (see Figure 5), which has managed to reduce the groove angles from 45 to 30 degrees with the new technology. The shipyard uses WPS documents based on welding procedure qualification records (WPQRs) for mechanized welding in the construction of icebreakers. “Adoption of the new technology has brought us cost savings and improved the welding quality,” says Arctech’s Hull Production Manager Niko Rautiainen. “Welding work has gained speed, because the groove volume and the number of beads to be welded have decreased. Also less filler material is needed. Mechanization has also improved the arc time ratio and made the welds more consistent in quality,” he adds.

Kemppi的RGT窄間隙焊接解決方案的用戶包(bao)括(kuo)Arctech赫爾(er)辛(xin)基造船(chuan)廠(chang)（見圖4），該造船廠利用新技術將槽角從45度減少到30度。在破冰船建造過(guo)程(cheng)中，造船廠使用基(ji)於焊接工藝評定記(ji)錄(lu)（WPQRS）的WPS文(wen)件進行機械化焊接。ARCTECH的船體(ti)生產經理Niko Rautiainen說(shuo)：“采用新技術為小黄瓜a视频在线節約了成(cheng)本，提高了焊接質量。”“由(you)於槽體積和待焊焊道數量減少，焊接工作加快(kuai)了。也需要更少的填充材料。機械化還提高了電弧時間比，使焊接質量更加一致，”他(ta)補(bu)充說。

Summary

總(zong)結

The RGT narrow gap welding solution developed by Kemppi is based on an intelligent control system that keeps the arc power consistent regardless of the variations in the contact-tip-to- work distance. In addition, the system controls the arc adaptively, to keep its energy density at the maximum level. A short, stable, and efficient arc minimizes the risk of incomplete penetration and lack of fusion, because the arc is always focused precisely at the desired point in the groove. The control system enables reliable narrow gap welding of materials with thicknesses of up to 30 mm, with a 20° groove angle, from one side, and without the need for special equipment or accessories. Smaller groove volume yields significant cost savings through reductions in welding time and filler-material consumption. The method is excellently suited to both butt and fillet joints, no matter the welding position.

Kemppi開發的RGT窄間隙焊接解決方案基於一個智能控製係統，該係統可使電弧功率保持一致，而不管(guan)接觸端(duan)到工作距離(li)的變化。此外，係統對電弧進行自適應控製，使其能量密度保持在最大水(shui)平。短、穩定和有效的電弧可將未焊透和未熔合的風險降至(zhi)最低，因(yin)為電弧總是精(jing)確聚(ju)焦在坡口中所需的點上。該控製係統能夠可靠地(di)從一側(ce)以20°槽角、厚度不超(chao)過30 mm的材料進行窄間隙焊接，無需特殊設備或附件。通過減少焊接時間和填充材料消耗，較小的槽體積可顯著節約成本。無論焊接位(wei)置(zhi)如何(he)，該方法(fa)都(dou)非常適用於對接接頭和角接接頭。
